Visible crew/equipment: When Eddie comments that the Rough Tough Cream Puff made a collar, she and Jamie walk up the hallway, and before Eddie reaches the doorway we can see the red tape mark on the floor as we hear Marcus brag, "mad fast." (00:15:55)
Continuity mistake: As Danny and Jaime are at the range shooting near the middle of the episode, their targets from behind and the grouping of shots they take are really tight together. When they retrieve their targets a minute later, the grouping from the front is completely different and further apart than what was seen from behind the target.
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?
