If you know your rights, it's a lot harder for police to fuck you over. You may think you know everything now, but this awesome video from the ACLU clears stuff up, and it's worth watching all 45 minutes. I'm posting this here obviously because BLTC is a hub for people who could be fucked over fairly easily for illegal activities, and hopefully it'll save some of you from fines/probation/jail.

1) Be respectful and as truthful as you can (but not to the point where it hurts you).
2) there is no step 2, just don't be an asshole to the cops.
