Doug MacRay: I need your help. I can't tell you what it is, you can never ask me about it later, and we're gonna hurt some people.
James Coughlin: Whose car we takin'?
FBI S.A. Adam Frawley: This is the "not fucking around" crew so get me something that looks like a print because this "not fucking around" thing is about to go both ways.
Claire Keesey: Did you say your name was Jim or Gem?
James Coughlin: Well, huh, it's kinda both. The teachers use to always say, "Here take this one. He's a gem."
Doug MacRay: We're fucked if we see a helicopter, we're fucked if we see SWAT. We see a cruiser, stop, take out the engine blocks, keep movin'. No one needs to get hurt.
James Coughlin: Yeah, these guards like to test you, though. They wanna get hurt for ten dollars an hour, don't get in the way.
James Coughlin: If we get jammed up, we're holding court on the street.
Doug MacRay: If I feel anything, if I think anything might happen to her... I'm gonna kill both of ya.
Answer: The bag of hair from the barbershop was used to throw off the police when they search the getaway car later. In other words they will find all the scattered hair and have the wrong DNA. This is what they do after the second heist. They never used one at the end since the cops already knew who they were.
