That's the way it looks to me. Question is, what were they up to?
Were they young or new? Could've just realized they made a mistake shooting at the illegal and panicked.
Supposedly made thousands of apprehensions without ever pulling their gun.
Wonder if maybe the smuggler was an inconvenient witness to something?
Maybe even if they weren't new.
Unlikely, though. The ones who do stupid stuff when they stress out do it early; the usual issues with longer-term guys is alcoholism and/or family problems--job performance is the very LAST thing to go.
