The prank guy got what he was looking for… but there is a problem: they were not out in the desert, they were inside a mall full of other people. You shouldn’t go “pew-pew” when every shot you miss can hit an innocent bystander.
Heck, even a shot that you don’t miss, can go all the way through and hit someone totally innocent on the other side.
