seriously - if you haven't checked out the show yet, add it to your netflix queue. NOW.
the first couple of episodes scared the crap out of me, because it felt a little too close to home. i live in a fairly diverse neighborhood, with a large african-american population. i have heard those shots, seen kids getting into some bad shit. but i persisted. and there is both hope and despair as you go along. it really becomes pretty riveting by the time you hit episode 6. the show is full of flawed characters flirting with redemption. redeeming characters riddled with flaws. it gets a little coarse at times, but the writing is fantastic.
and once you are well into it, inspire yourself with this
