Continuity mistake: Danny and Jamie are at the pistol range shooting targets. The vantage point from down range shows them both shooting tight shot groups. However, when they are finished shooting, they hold up their targets; their shot groups are not as tight as the down range perspective. (00:34:01)
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.

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?
I think it may be Masonic?
But why would the mayor wear one?
