Continuity mistake: Danny and the ESU enter the warehouse basement to find Bobby, and when they start to return fire, the first guy they shoot knocks over the white plastic lawn chair (beside the recliner) as he goes down. Then, in the next shot facing the door, that white lawn chair is upright (not the yellow table chairs), but in the next shot it's lying on the floor again. (00:32:40)
Plot hole: Jamie and his witness are in a patrol car when they are attacked by criminals in a van firing machine guns at them. Jamie (of course) chases them away after a prolonged firefight, and when the van is driving away we see another patrol car also shooting at the fleeing suspects. There didn't appear to be any cars with Jamie, nor did anyone come to his aid during the gunfight, and this other patrol car was facing the wrong direction.
Plot hole: Early in the show, Jamie is in a patrol car escorting a witness when they are attacked by several guys in a van. The side windows of their cruiser seem shatterproof and withstand many bullets, while the rear window is shattered immediately. NYPD cruisers do not have bulletproof windows.
Answer: It is the lapel pin worn by members of the NYPD Honor Legion.
The lapel pin is on Danny but not Biaz, why? Also, Baker, Sid, Frank &Garrett wear one. Significance? Are they all the same?
Is the P.C.'s pin different than a legion pin? What are the symbols and their meaning?
But why would the mayor wear one?
