The Wire, Season 3

Colvin:
Somewhere back in the beginning of time, this district had itself a civic dilemma of epic proportions. The city council had just passed a law that forbade alcoholic consumption in public areas; on the streets and on the corners. But the corner is, it was and it always will be the poorman's lounge. It's where a man wants to be on a hot summer's night. It's cheaper than a bar. Catch a nice breeze and watch the girls go on by. But the law is the law so what are the western cops gonna do? They arrest every dude for tipping back a High Life, there'd be no time for any other kind of police work. And if they look the other way, they open themselves up to all kinds of flaunting, all kinds of disrespect. Now, this is before my time but somewhere back in the 50's or the 60's, there was a moment of goddamn genius by some nameless smokehound who comes out the Cut-Rate one day and on his way to the corner he slips that just bought pint of elderberry into a paper bag. A great moment of civic compromise. That small wrinkled ass paper bag allowed the corner boys to have their drink in peace and gave us permission to go and do police work. The kind of police work that's actually worth the effort, that's actually worth taking a bullet for. Dozerman got shot last night buying three vials. Three. There has never been a paper bag for drugs. Until now.
