Homicide: Life on the Street1993

Det. Frank Pembleton:
You're history. And if the detective wasn't so busy typing up your statement, he'd probably tell you so. He'd say, 'Son, you are ignorance personified, and you just put yourself in for the murder of another human being'. He might even admit to you that after all his time working murders, he's still amazed that anyone utters a word in this room. Think about it, son. When you came through those doors, what did the sign say? Homicide Unit, that's right. And who lives in a Homicide Unit? And what do homicide detectives do for a living? You got it, bunk. And tonight you took someone's life. So when you opened your mouth, what in God's name were you thinkin'?
