From "Little Brother", by Cory Doctorow, Tor Teen (2008):

-------------------------------------------------------------------
I moved down the corridor lightly and sprightly, keeping my
gate even and measured for the gait-recognition cameras. These had
been installed only a year before, and I loved them for their sheer
idiocy. Beforehand, we'd had face-recognition cameras covering
nearly every public space in school, but a court ruled that was
unconstitutional. So Benson and a lot of other paranoid school
administrators had spent our textbook dollars on these idiot cameras
that were supposed to be able to tell one person's walk from another.
Yeah, right."

Neil Gamon writes in the Amazon review of this book:

“A wonderful, important book…I’d recommend Little Brother over pretty much
any book I’ve read this year, and I’d want to get it into the hands
of as many smart thirteen-year-olds, male and female, as I can.
Because I think it’ll change lives. Because some kids, maybe just a few,
won’t be the same after they’ve read it. Maybe they’ll change politically,
maybe technologically. Maybe it’ll just be the first book they loved
or that spoke to their inner geek. Maybe they’ll want to argue about it
and disagree with it. Maybe they’ll want to open their computer and see
what’s in there. I don’t know. It made me want to be thirteen again right now,
and reading it for the first time.”
