Patriots Day (2016)

Continuity mistake: When Mark Wahlberg approaches the boat, an officer following behind him pulls out his pistol from his holster. But in the next shot, the officer holsters a radio which has suddenly appeared in his hand, and pulls out his pistol again. (01:52:40)

Dun Meng: Go catch those motherfuckers.

Question: Was Dzhokhar really slapped to the ground from off the boat as depicted in the movie? Or was that exaggerated to show the finality of the authorities finally getting him?
