Dude, have you ever heard of the saying, "you are judged by the company you keep"? Maybe people like the police wouldn't see you as somebody who's involved in this sort of stuff if you didn't hang around with people who are, and if you didn't go around trumpeting your involvement to all and sundry, like the stabbing incident.

You can't blame people for having an opinion about you based on what you've said on here! You claim you want help or advice, but the second anything negative is said about you, you become abusive! Hardly a mature response, wouldn't you say? Crazypthead is right, you need to take a close look at your life, and instead of either being the "badass hero" when it suits or alternatively the martyr when you don't get a response you'd like, maybe you could try acting like a responsible or even normal person?
