Plot hole: These guys supposedly rob banks in Boston and then high tail it back to "safety" in Charlestown. In one chase the police even screech to a halt at the city limits. First of all, Charlestown is not a separate city, it's a neighborhood within Boston so that idea doesn't hold water. Second, police can continue a chase past city lines anyway.
Suggested correction: The cop cars only "screech to a halt" because they are intentionally blocking the bridge to Charlestown. At that point they had switched cars and there were no police actively on their tail, so the police didn't realise they were too late in blocking the bridge.
Other mistake: Claire Keesey the bank manager has the birthday May 19, 1978, making her age 30. That doesn't align with the crime witness date for 9/2011 - she should be 33. (02:41:15)
Other mistake: When robbing the bank at the beginning of the movie, Claire is somehow about to see the tattoo on the back of Gem's neck while he is standing, and she's lying on the floor looking up.
