Read Thompson's "Hells Angels". He made the mistake of thinking they were his friends and almost got beaten to death. It's like the old story about the turtle that helped the snake across the river. The snake bit him after he got to the other side. The turtle said why, I just helped you and the snake said I am still a snake. This is huge paraphrase, but you have to remember what and who you are dealing with, with the Hells Angel's and their ilk.
