Wow, I thought Baltimore cops didn't care about skaters, because theres a lot of crime. Cops are stupid, one looked inside my backpack and held up a pair of pants and said "he's got a jacket in here".
The cop in that video was obviously a fucking prick, however, once an officer speaks to you and calls you out for anything, you just have to realize you've been defeated; you're done. Don't try to do anything smart, just co-operate. It's amazing how easily situations can be avoided by just co-operating.
