Whats the guy supposed to do, just shoot up in the air? Or maybe carefully aim and shot by his foot just enough threaten him? Or maybe just show the gun to this much bigger guy whos already harrassing him? Any of those situations could either result in a bystander getting hit, or the victim getting killed when his assualter pulls his own gun out.
He did the right thing to protect himself. However he should not have been placed into this situation, all the fault should fall on the aggressor. But instead this victim is being held in jail and might be charged a felony for protecting himself from some deranged youtube asshole, WHO IS PROFITTING FROM THIS CRIME. The victim wouldve been better off if he had got a kill shot.
