A first-person account of an arrest:

I stared at the yellow walls and listened to a few officers talk about the overtime they were racking up, and I decided that I hated country music. I hated speedboats and shitty beer in coozies and fat bellies and rednecks. I thought about Abu Ghraib and the horror to which those prisoners were exposed. I thought about my dad and his prescience. I was glad he wasn’t alive to know about what was happening to me. I thought about my kids, and what would have happened if they had been there when I got taken away. I contemplated never flying again. I thought about the incredible waste of taxpayer dollars in conducting an operation like this. I wondered what my rights were, if I had any at all. Mostly, I could not believe I was sitting in some jail cell in some cold, undisclosed building surrounded by “the authorities.”
