Chapter 6

[[This chapter is dedicated to Powell's Books, the legendary "City of

Books" in Portland, Oregon. Powell's is the largest bookstore in the

world, an endless, multi-storey universe of papery smells and towering

shelves. They stock new and used books on the same shelves -- something

I've always loved -- and every time I've stopped in, they've had a

veritable mountain of my books, and they've been incredibly gracious

about asking me to sign the store-stock. The clerks are friendly, the

stock is fabulous, and there's even a Powell's at the Portland airport,

making it just about the best airport bookstore in the world for my

money!]]

Believe it or not, my parents made me go to school the next day. I'd

only fallen into feverish sleep at three in the morning, but at seven

the next day, my Dad was standing at the foot of my bed, threatening to

drag me out by the ankles. I managed to get up -- something had died in

my mouth after painting my eyelids shut -- and into the shower.

I let my mom force a piece of toast and a banana into me, wishing

fervently that my parents would let me drink coffee at home. I could

sneak one on the way to school, but watching them sip down their black

gold while I was drag-assing around the house, getting dressed and

putting my books in my bag -- it was awful.

I've walked to school a thousand times, but today it was different. I

went up and over the hills to get down into the Mission, and everywhere

there were trucks. I saw new sensors and traffic cameras installed at

many of the stop-signs. Someone had a lot of surveillance gear lying

around, waiting to be installed at the first opportunity. The attack on

the Bay Bridge had been just what they needed.

It all made the city seem more subdued, like being inside an elevator,

embarrassed by the close scrutiny of your neighbors and the ubiquitous

cameras.

The Turkish coffee shop on 24th Street fixed me up good with a go-cup

of Turkish coffee. Basically, Turkish coffee is mud, pretending to be

coffee. It's thick enough to stand a spoon up in, and it has way more

caffeine than the kiddee-pops like Red Bull. Take it from someone who's

read the Wikipedia entry: this is how the Ottoman Empire was won:

maddened horsemen fueled by lethal jet-black coffee-mud.

I pulled out my debit card to pay and he made a face. "No more debit,"

he said.

"Huh? Why not?" I'd paid for my coffee habit on my card for years at

the Turk's. He used to hassle me all the time, telling me I was too

young to drink the stuff, and he still refused to serve me at all

during school hours, convinced that I was skipping class. But over the

years, the Turk and me have developed a kind of gruff understanding.

He shook his head sadly. "You wouldn't understand. Go to school, kid."

There's no surer way to make me want to understand than to tell me I

won't. I wheedled him, demanding that he tell me. He looked like he was

going to throw me out, but when I asked him if he thought I wasn't good

enough to shop there, he opened up.

"The security," he said, looking around his little shop with its tubs

of dried beans and seeds, its shelves of Turkish groceries. "The

government. They monitor it all now, it was in the papers. PATRIOT Act

II, the Congress passed it yesterday. Now they can monitor every time

you use your card. I say no. I say my shop will not help them spy on my

customers."

My jaw dropped.

"You think it's no big deal maybe? What is the problem with government

knowing when you buy coffee? Because it's one way they know where you

are, where you been. Why you think I left Turkey? Where you have

government always spying on the people, is no good. I move here twenty

years ago for freedom -- I no help them take freedom away."

"You're going to lose so many sales," I blurted. I wanted to tell him

he was a hero and shake his hand, but that was what came out. "Everyone

uses debit cards."

"Maybe not so much anymore. Maybe my customers come here because they

know I love freedom too. I am making sign for window. Maybe other

stores do the same. I hear the ACLU will sue them for this."

"You've got all my business from now on," I said. I meant it. I reached

into my pocket. "Um, I don't have any cash, though."

He pursed his lips and nodded. "Many peoples say the same thing. Is OK.

You give today's money to the ACLU."

In two minutes, the Turk and I had exchanged more words than we had in

all the time I'd been coming to his shop. I had no idea he had all

these passions. I just thought of him as my friendly neighborhood

caffeine dealer. Now I shook his hand and when I left his store, I felt

like he and I had joined a team. A secret team.

I'd missed two days of school but it seemed like I hadn't missed much

class. They'd shut the school on one of those days while the city

scrambled to recover. The next day had been devoted, it seemed, to

mourning those missing and presumed dead. The newspapers published

biographies of the lost, personal memorials. The Web was filled with

these capsule obituaries, thousands of them.

Embarrassingly, I was one of those people. I stepped into the

schoolyard, not knowing this, and then there was a shout and a moment

later there were a hundred people around me, pounding me on the back,

shaking my hand. A couple girls I didn't even know kissed me, and they

were more than friendly kisses. I felt like a rock star.

My teachers were only a little more subdued. Ms Galvez cried as much as

my mother had and hugged me three times before she let me go to my desk

and sit down. There was something new at the front of the classroom. A

camera. Ms Galvez caught me staring at it and handed me a permission

slip on smeary Xeroxed school letterhead.

The Board of the San Francisco Unified School District had held an

emergency session over the weekend and unanimously voted to ask the

parents of every kid in the city for permission to put closed circuit

television cameras in every classroom and corridor. The law said they

couldn't force us to go to school with cameras all over the place, but

it didn't say anything about us *volunteering* to give up our

Constitutional rights. The letter said that the Board were sure that

they would get complete compliance from the City's parents, but that

they would make arrangements to teach those kids' whose parents

objected in a separate set of "unprotected" classrooms.

Why did we have cameras in our classrooms now? Terrorists. Of course.

Because by blowing up a bridge, terrorists had indicated that schools

were next. Somehow that was the conclusion that the Board had reached

anyway.

I read this note three times and then I stuck my hand up.

"Yes, Marcus?"

"Ms Galvez, about this note?"

"Yes, Marcus."

"Isn't the point of terrorism to make us afraid? That's why it's called

*terror*ism, right?"

"I suppose so." The class was staring at me. I wasn't the best student

in school, but I did like a good in-class debate. They were waiting to

hear what I'd say next.

"So aren't we doing what the terrorists want from us? Don't they win if

we act all afraid and put cameras in the classrooms and all of that?"

There was some nervous tittering. One of the others put his hand up. It

was Charles. Ms Galvez called on him.

"Putting cameras in makes us safe, which makes us less afraid."

"Safe from what?" I said, without waiting to be called on.

"Terrorism," Charles said. The others were nodding their heads.

"How do they do that? If a suicide bomber rushed in here and blew us

all up --"

"Ms Galvez, Marcus is violating school policy. We're not supposed to

make jokes about terrorist attacks --"

"Who's making jokes?"

"Thank you, both of you," Ms Galvez said. She looked really unhappy. I

felt kind of bad for hijacking her class. "I think that this is a

really interesting discussion, but I'd like to hold it over for a

future class. I think that these issues may be too emotional for us to

have a discussion about them today. Now, let's get back to the

suffragists, shall we?"

So we spent the rest of the hour talking about suffragists and the new

lobbying strategies they'd devised for getting four women into every

congresscritter's office to lean on him and let him know what it would

mean for his political future if he kept on denying women the vote. It

was normally the kind of thing I really liked -- little guys making the

big and powerful be honest. But today I couldn't concentrate. It must

have been Darryl's absence. We both liked Social Studies and we would

have had our SchoolBooks out and an IM session up seconds after sitting

down, a back-channel for talking about the lesson.

I'd burned twenty ParanoidXbox discs the night before and I had them

all in my bag. I handed them out to people I knew were really, really

into gaming. They'd all gotten an Xbox Universal or two the year

before, but most of them had stopped using them. The games were really

expensive and not a lot of fun. I took them aside between periods, at

lunch and study hall, and sang the praises of the ParanoidXbox games to

the sky. Free and fun -- addictive social games with lots of cool

people playing them from all over the world.

Giving away one thing to sell another is what they call a "razor blade

business" -- companies like Gillette give you free razor-blade handles

and then stiff you by charging you a small fortune for the blades.

Printer cartridges are the worst for that -- the most expensive

Champagne in the world is cheap when compared with inkjet ink, which

costs all of a penny a gallon to make wholesale.

Razor-blade businesses depend on you not being able to get the "blades"

from someone else. After all, if Gillette can make nine bucks on a

ten-dollar replacement blade, why not start a competitor that makes

only four bucks selling an identical blade: an 80 percent profit margin

is the kind of thing that makes your average business-guy go all drooly

and round-eyed.

So razor-blade companies like Microsoft pour a lot of effort into

making it hard and/or illegal to compete with them on the blades. In

Microsoft's case, every Xbox has had countermeasures to keep you from

running software that was released by people who didn't pay the

Microsoft blood-money for the right to sell Xbox programs.

The people I met didn't think much about this stuff. They perked up

when I told them that the games were unmonitored. These days, any

online game you play is filled with all kinds of unsavory sorts. First

there are the pervs who try to get you to come out to some remote

location so they can go all weird and Silence of the Lambs on you. Then

there are the cops, who are pretending to be gullible kids so they can

bust the pervs. Worst of all, though, are the monitors who spend all

their time spying on our discussions and snitching on us for violating

their Terms of Service, which say, no flirting, no cussing, and no

"clear or masked language which insultingly refers to any aspect of

sexual orientation or sexuality."

I'm no 24/7 horn-dog, but I'm a seventeen year old boy. Sex does come

up in conversation every now and again. But God help you if it came up

in chat while you were gaming. It was a real buzz-kill. No one

monitored the ParanoidXbox games, because they weren't run by a

company: they were just games that hackers had written for the hell of

it.

So these game-kids loved the story. They took the discs greedily, and

promised to burn copies for all of their friends -- after all, games

are most fun when you're playing them with your buddies.

When I got home, I read that a group of parents were suing the school

board over the surveillance cameras in the classrooms, but that they'd

already lost their bid to get a preliminary injunction against them.

I don't know who came up with the name Xnet, but it stuck. You'd hear

people talking about it on the Muni. Van called me up to ask me if I'd

heard of it and I nearly choked once I figured out what she was talking

about: the discs I'd started distributing last week had been

sneakernetted and copied all the way to Oakland in the space of two

weeks. It made me look over my shoulder -- like I'd broken a rule and

now the DHS would come and take me away forever.

They'd been hard weeks. The BART had completely abandoned cash fares

now, switching them for arphid "contactless" cards that you waved at

the turnstiles to go through. They were cool and convenient, but every

time I used one, I thought about how I was being tracked. Someone on

Xnet posted a link to an Electronic Frontier Foundation white paper on

the ways that these things could be used to track people, and the paper

had tiny stories about little groups of people that had protested at

the BART stations.

I used the Xnet for almost everything now. I'd set up a fake email

address through the Pirate Party, a Swedish political party that hated

Internet surveillance and promised to keep their mail accounts a secret

from everyone, even the cops. I accessed it strictly via Xnet, hopping

from one neighbor's Internet connection to the next, staying anonymous

-- I hoped -- all the way to Sweden. I wasn't using w1n5ton anymore. If

Benson could figure it out, anyone could. My new handle, come up with

on the spur of the moment, was M1k3y, and I got a *lot* of email from

people who heard in chat rooms and message boards that I could help

them troubleshoot their Xnet configurations and connections.

I missed Harajuku Fun Madness. The company had suspended the game

indefinitely. They said that for "security reasons" they didn't think

it would be a good idea to hide things and then send people off to find

them. What if someone thought it was a bomb? What if someone put a bomb

in the same spot?

What if I got hit by lightning while walking with an umbrella? Ban

umbrellas! Fight the menace of lightning!

I kept on using my laptop, though I got a skin-crawly feeling when I

used it. Whoever had wiretapped it would wonder why I didn't use it. I

figured I'd just do some random surfing with it every day, a little

less each day, so that anyone watching would see me slowly changing my

habits, not doing a sudden reversal. Mostly I read those creepy obits

-- all those thousands of my friends and neighbors dead at the bottom

of the Bay.

Truth be told, I *was* doing less and less homework every day. I had

business elsewhere. I burned new stacks of ParanoidXbox every day,

fifty or sixty, and took them around the city to people I'd heard were

willing to burn sixty of their own and hand them out to their friends.

I wasn't too worried about getting caught doing this, because I had

good crypto on my side. Crypto is cryptography, or "secret writing,"

and it's been around since Roman times (literally: Augustus Caesar was

a big fan and liked to invent his own codes, some of which we use today

for scrambling joke punchlines in email).

Crypto is math. Hard math. I'm not going to try to explain it in detail

because I don't have the math to really get my head around it, either

-- look it up on Wikipedia if you really want.

But here's the Cliff's Notes version: Some kinds of mathematical

functions are really easy to do in one direction and really hard to do

in the other direction. It's easy to multiply two big prime numbers

together and make a giant number. It's really, really hard to take any

given giant number and figure out which primes multiply together to

give you that number.

That means that if you can come up with a way of scrambling something

based on multiplying large primes, unscrambling it without knowing

those primes will be hard. Wicked hard. Like, a trillion years of all

the computers ever invented working 24/7 won't be able to do it.

There are four parts to any crypto message: the original message,

called the "cleartext." The scrambled message, called the "ciphertext."

The scrambling system, called the "cipher." And finally there's the

key: secret stuff you feed into the cipher along with the cleartext to

make ciphertext.

It used to be that crypto people tried to keep all of this a secret.

Every agency and government had its own ciphers *and* its own keys. The

Nazis and the Allies didn't want the other guys to know how they

scrambled their messages, let alone the keys that they could use to

descramble them. That sounds like a good idea, right?

Wrong.

The first time anyone told me about all this prime factoring stuff, I

immediately said, "No way, that's BS. I mean, *sure* it's hard to do

this prime factorization stuff, whatever you say it is. But it used to

be impossible to fly or go to the moon or get a hard-drive with more

than a few kilobytes of storage. Someone *must* have invented a way of

descrambling the messages." I had visions of a hollow mountain full of

National Security Agency mathematicians reading every email in the

world and snickering.

In fact, that's pretty much what happened during World War II. That's

the reason that life isn't more like Castle Wolfenstein, where I've

spent many days hunting Nazis.

The thing is, ciphers are hard to keep secret. There's a lot of math

that goes into one, and if they're widely used, then everyone who uses

them has to keep them a secret too, and if someone changes sides, you

have to find a new cipher.

The Nazi cipher was called Enigma, and they used a little mechanical

computer called an Enigma Machine to scramble and unscramble the

messages they got. Every sub and boat and station needed one of these,

so it was inevitable that eventually the Allies would get their hands

on one.

When they did, they cracked it. That work was led by my personal

all-time hero, a guy named Alan Turing, who pretty much invented

computers as we know them today. Unfortunately for him, he was gay, so

after the war ended, the stupid British government forced him to get

shot up with hormones to "cure" his homosexuality and he killed

himself. Darryl gave me a biography of Turing for my 14th birthday --

wrapped in twenty layers of paper and in a recycled Batmobile toy, he

was like that with presents -- and I've been a Turing junkie ever

since.

Now the Allies had the Enigma Machine, and they could intercept lots of

Nazi radio-messages, which shouldn't have been that big a deal, since

every captain had his own secret key. Since the Allies didn't have the

keys, having the machine shouldn't have helped.

Here's where secrecy hurts crypto. The Enigma cipher was flawed. Once

Turing looked hard at it, he figured out that the Nazi cryptographers

had made a mathematical mistake. By getting his hands on an Enigma

Machine, Turing could figure out how to crack *any* Nazi message, no

matter what key it used.

That cost the Nazis the war. I mean, don't get me wrong. That's good

news. Take it from a Castle Wolfenstein veteran. You wouldn't want the

Nazis running the country.

After the war, cryptographers spent a lot of time thinking about this.

The problem had been that Turing was smarter than the guy who thought

up Enigma. Any time you had a cipher, you were vulnerable to someone

smarter than you coming up with a way of breaking it.

And the more they thought about it, the more they realized that

*anyone* can come up with a security system that he can't figure out

how to break. But *no one* can figure out what a smarter person might

do.

You have to publish a cipher to know that it works. You have to tell

*as many people as possible* how it works, so that they can thwack on

it with everything they have, testing its security. The longer you go

without anyone finding a flaw, the more secure you are.

Which is how it stands today. If you want to be safe, you don't use

crypto that some genius thought of last week. You use the stuff that

people have been using for as long as possible without anyone figuring

out how to break them. Whether you're a bank, a terrorist, a government

or a teenager, you use the same ciphers.

If you tried to use your own cipher, there'd be the chance that someone

out there had found a flaw you missed and was doing a Turing on your

butt, deciphering all your "secret" messages and chuckling at your dumb

gossip, financial transactions and military secrets.

So I knew that crypto would keep me safe from eavesdroppers, but I

wasn't ready to deal with histograms.

I got off the BART and waved my card over the turnstile as I headed up

to the 24th Street station. As usual, there were lots of weirdos

hanging out in the station, drunks and Jesus freaks and intense Mexican

men staring at the ground and a few gang kids. I looked straight past

them as I hit the stairs and jogged up to the surface. My bag was empty

now, no longer bulging with the ParanoidXbox discs I'd been

distributing, and it made my shoulders feel light and put a spring in

my step as I came up the street. The preachers were at work still,

exhorting in Spanish and English about Jesus and so on.

The counterfeit sunglass sellers were gone, but they'd been replaced by

guys selling robot dogs that barked the national anthem and would lift

their legs if you showed them a picture of Osama bin Laden. There was

probably some cool stuff going on in their little brains and I made a

mental note to pick a couple of them up and take them apart later.

Face-recognition was pretty new in toys, having only recently made the

leap from the military to casinos trying to find cheats, to law

enforcement.

I started down 24th Street toward Potrero Hill and home, rolling my

shoulders and smelling the burrito smells wafting out of the

restaurants and thinking about dinner.

I don't know why I happened to glance back over my shoulder, but I did.

Maybe it was a little bit of subconscious sixth-sense stuff. I knew I

was being followed.

They were two beefy white guys with little mustaches that made me think

of either cops or the gay bikers who rode up and down the Castro, but

gay guys usually had better haircuts. They had on windbreakers the

color of old cement and blue-jeans, with their waistbands concealed. I

thought of all the things a cop might wear on his waistband, of the

utility-belt that DHS guy in the truck had worn. Both guys were wearing

Bluetooth headsets.

I kept walking, my heart thumping in my chest. I'd been expecting this

since I started. I'd been expecting the DHS to figure out what I was

doing. I took every precaution, but Severe-Haircut woman had told me

that she'd be watching me. She'd told me I was a marked man. I realized

that I'd been waiting to get picked up and taken back to jail. Why not?

Why should Darryl be in jail and not me? What did I have going for me?

I hadn't even had the guts to tell my parents -- or his -- what had

really happened to us.

I quickened my steps and took a mental inventory. I didn't have

anything incriminating in my bag. Not too incriminating, anyway. My

SchoolBook was running the crack that let me IM and stuff, but half the

people in school had that. I'd changed the way I encrypted the stuff on

my phone -- now I *did* have a fake partition that I could turn back

into cleartext with one password, but all the good stuff was hidden,

and needed another password to open up. That hidden section looked just

like random junk -- when you encrypt data, it becomes indistinguishable

from random noise -- and they'd never even know it was there.

There were no discs in my bag. My laptop was free of incriminating

evidence. Of course, if they thought to look hard at my Xbox, it was

game over. So to speak.

I stopped where I was standing. I'd done as good a job as I could of

covering myself. It was time to face my fate. I stepped into the

nearest burrito joint and ordered one with carnitas -- shredded pork --

and extra salsa. Might as well go down with a full stomach. I got a

bucket of horchata, too, an ice-cold rice drink that's like watery,

semi-sweet rice-pudding (better than it sounds).

I sat down to eat, and a profound calm fell over me. I was about to go

to jail for my "crimes," or I wasn't. My freedom since they'd taken me

in had been just a temporary holiday. My country was not my friend

anymore: we were now on different sides and I'd known I could never

win.

The two guys came into the restaurant as I was finishing the burrito

and going up to order some churros -- deep-fried dough with cinnamon

sugar -- for dessert. I guess they'd been waiting outside and got tired

of my dawdling.

They stood behind me at the counter, boxing me in. I took my churro

from the pretty granny and paid her, taking a couple of quick bites of

the dough before I turned around. I wanted to eat at least a little of

my dessert. It might be the last dessert I got for a long, long time.

Then I turned around. They were both so close I could see the zit on

the cheek of the one on the left, the little booger up the nose of the

other.

"'Scuse me," I said, trying to push past them. The one with the booger

moved to block me.

"Sir," he said, "can you step over here with us?" He gestured toward

the restaurant's door.

"Sorry, I'm eating," I said and moved again. This time he put his hand

on my chest. He was breathing fast through his nose, making the booger

wiggle. I think I was breathing hard too, but it was hard to tell over

the hammering of my heart.

The other one flipped down a flap on the front of his windbreaker to

reveal a SFPD insignia. "Police," he said. "Please come with us."

"Let me just get my stuff," I said.

"We'll take care of that," he said. The booger one stepped right up

close to me, his foot on the inside of mine. You do that in some

martial arts, too. It lets you feel if the other guy is shifting his

weight, getting ready to move.

I wasn't going to run, though. I knew I couldn't outrun fate.
