Sgt. Mick Belker: [Detective Brooks has been murdered while working undercover] I told you, but you wouldn't listen. I told you we shoulda pulled him out of there right after the warehouse bust. I begged you. And on the phone, when he didn't show up for his wire, he kept telling me to "wait"...
Lt. Ray Calletano: Mick, it wouldn't have changed anything.
Sgt. Mick Belker: How do we know that? He had it all ahead of him, and you threw his life away. His death is on your head.
Capt. Frank Furillo: They all are, Mick.
