This morning I finished season one of The Wire, HBO's long-running cop show. And if I didn't love it for its pragmatic worldview, its left-leaning sociological outlook, and its flawed protagonists, I would almost certainly love it just for this scene of McNulty and Bunk investigating an old murder scene.
I guess it's not explicitly clear from that scene, but the writing is superb, and usually not composed entirely of profanity.
