Capt. Gates: Are you sure about this?
Beckett: Yes, sir, but the moment I file a warrant request for that coat, it becomes public record.
Capt. Gates: So?
Beckett: So then everyone will know that Mayor Weldon is a person of interest.
Capt. Gates: Isn't he?
Beckett: Yes, but... what if I'm wrong? It could ruin his career.
Capt. Gates: We... are tasked by the city of New York to protect its people. Sometimes that task comes with a cost. I know what they call me, detective, Iron Gates. I hear the whispers. She's from IA. She must hate cops. Well, the truth is, I love cops. My daddy was a cop. My uncles were cops. But the sergeant who assaulted my patrol partner under the color or authority... who holds him accountable? We do. Go to the mayor, get him to voluntarily surrender his coat for fiber testing without a warrant. Tell him it's the only way to keep it out of the media. But if he refuses, you get that warrant and you do your job, whatever the cost.
