Adrenalin my friend. Plus Brazil is a drug ridden country, thus the high crime rate. Thugs were looking for drug cash, not retirement funds so they may have been high on something. First shot most likely connected with the dude, but the second looks like it whizzed over the second thug head. You can go a long way on that adrenalin. That's why you need the two to the chest and one to the melon drill.
