Your right man, I totally agree HOWEVA-Scabadus said:What if the man had not been yelling at the TV/games? What if he was yelling stuff like "I'm going to kill you! I'm going to rip your arms off and stab you!" and had actually been shouting at a person he had trapped in his house? Would it have been fair for the police to call SWAT then?
Now the the event is over we know he was not, but we don't know the full facts and it was possible the police thought he was a geuine threat. Either way, we don't have the information here that the police had there; their reactions could have been perfectly reasonable to the situation.
I would have pumped that little shit-bag full of beanbag rounds and stormed the house.
