Here's a collection of photos from Sydney, Australia's Justice & Police Museum exhibition Crooks. These pictures were taken by Australian police in the 1920s, capturing "individuals they thought were, or were likely to become, professional criminals." They're collected in a high-quality photography book called Crooks Like Us, which non-Australians can also get a pretty good deal on at Amazon. The photos themselves are striking and their subjects run the gamut from properly scary villains to haunted and troubled souls.
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.
