I know a cop. A vice detective, really. He is related to me by marriage.

I know another cop, a head of state vice.

Both have made it clear - they don't care about weed so much. But if they see it, or know about it, they have to do something about it. It's their job.

The long and short of the story is like many others have said before - don't give them a reason to fuck with you and they won't. It is a job, like any other. It's easy to say "fuck the police" but the truth of the matter is that they provide a vital function in society. Don't be a dumb ass - respect their authority, be legit (other than smoking bud) and they are cool. BUT - if you show attitude, flaunt it in their faces, then you get what's coming to you.

I will say that some are dicks who probably got beaten in high school and are now looking for payback. Suck it up and take it. Jail sucks, being in the system sucks. Don't risk it. They will make your life hell and get those otherwise cool cops after your ass as well. It is a brotherhood. They will shake you down for the hell of it - because you show disrespect to their job. Like it or not, the average cop sees things black or white when it comes to the law.
