It is a manifesto. That was just the second part of it. The first part deals with how he was allegedly wronged by the LAPD. He explains why he is doing what hes doing. Says that hes going to essentially get everyone involved one by one. Scary stuff. By reading it It sure sounds like he was screwed over big time but this is absolutely no way to deal with it.
As for his circus comments on the Jets... cant argue.
