Difficult to know, scrubmuncher. Sounded like shots but no victims visible on that tape, so whether anyone was killed or not we wouldn't be able to say, from that. The foreigners sounded a bit scared but also jocular, so, who knows? We'll just have to hope the shooter wasn't using your gun, eh?
I just noticed the scruffy looking dude walking (in a mission kinda way) in 10 secs before the shots went off, that sort of brought out the columbo in me and put 2 and 3 together. Maths never a strong point guys.
