Hat tip to @Shaderabbit (You must spread some Reputation around before giving it to ShadeRabbit again) for noticing the Pittsburg Gopher.

Starting at the .26-27 mark, watch his right hand.
The dude stands up and scans towards the source of drama.
Only at the .40 mark does he exit stage right (below)

<- who is the curious mystery white dude?

$20 says he was
1) carrying
and
2) has a pre-existing arrest record.

Gotta give him props for a good tactical response (orient toward threat, scan for targets, hold fire until target[s] identified and
- if no action required or possible - get off the X).
