That Nick Davies book is great.
I think people here might enjoy Chav Solidarity by D Hunter too - abject memoir from the UK:
Two days after I ran away from home that first time, after spending the first night sleeping underneath a tree at the top of the Forest Rec, I tried to rob a man in a wheelchair. I saw him moving through the park alone, and it was dark so I thought I could handle it. I raced up behind him holding a small knife and before I could hold it to him he'd swung his wheel chair and slapped me to the ground. I don't really remember what words were spoken, but he managed to have his hands around my neck pretty tightly pretty quickly. He made it clear that I was going to suck him off or he was going to kill me then and there. I have no idea if he was someone capable of that, as I was a couple of years away from being able to make that judgement. I found his dick inside my mouth, and he moved my head up and down until he came inside. Once he had emptied himself he lifted my head up and drove it against his forehead. The next thing I knew I saw him on the floor, his wheel chair a good five feet away and three kids, a little older than me kicking the crap out of him. I watched this from the floor for a couple of minutes, before one of the kids turned around and walked over to me. She offered her hand and helped me up, and as she did so indicated the man on the floor. I think she must have said it, but maybe she didn't, either way it was enough for me to understand that I should give the man a few healthy kicks.
