It's the oddest trade show on Earth: a staged prison uprising designed to spotlight high-tech antiriot gadgetry.
Fifteen convicts are rioting in J-Block. They've already beaten one officer to a pulp, and a murderous 24-year-old named Kevin Maloney has a homemade knife to the throat of a second. The time for negotiation is over. Adrenaline pumping, weapons ready, helmets and gas masks on, 12 corrections officers and I take position under a set of stairs. "I need a yard of separation," Captain Carl Sims whispers over the radio to Batina Thornhill, our negotiator. A moment later, she gets it for him, tricking Maloney into approaching her without his hostage.
