British local councils have a new weapon in their arsenal of devices that collectively and indiscriminately punish teenagers simply for being young. The new tool is a pink overhead light designed to exaggerate acne, with the intention of making children so unhappy and insecure about their appearances that they go somewhere else (mind you, these councils are almost certainly also allocating funds to helping teenagers cope with low self-esteem and avoid the problems associated with it, such as depression and vulnerability of recruitment into violent activity).
Other weapons in the arsenal against youth include the "Mosquito" -- an annoying high-pitched tone that adults can't hear, that shopkeepers and councils have deployed against teens and kids (and, of course, any babies that happen to be in the area), and "anti-kid steps" that are supposed to prevent the menace of kids staying in one place, talking to one another.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
