IMHO, First and foremost all four men got out of the vehicle with firearms, one had an AK, another looked to have some small tech 9 or uzi style weapon, and the other two had hand guns at a minimum, that is an awful lot of firepower for a mere disagreement. They rushed the house, so the owner layed down supresive fire, the guys then ran for cover, at that point the one with the AK turned and pointed the gun towards the house, as well as the guy with the sub gun, the other two with the small arms ran down the street. The driver then grabbed a hand gun, while trying to retrieve his car, and pointed it towards the house again, looks as if he got a defencive shot or two off, with that in mind, he was still the aggressor, and the home owner returned fire. Seems pretty open and shut from a self defence point of veiw. The wild card would be, the rounds that made it to his neighbors homes and hit the other houses, they are not saying who's gun they came from. Was he justified with the actions he took? No contest YES, in MA he may have a problem with the rounds hitting his neighbors houses, if they are from his gun. If it was from the trespassers than I think he would be fine. But then again this is MA and the guys who were breaking the law, they had rights too, and should not of had to endure the emotional stress the victim caused to them. He would be found guilty by some left leaning liberal judge/jury, of causing undue stress and attempted murder, serve 2 years, on probation for life , would need to attend anger managment classes for the next decade ,have his firearms taken, and would have to sell everything to settle the civil lawsuit. If I have missed anything, please chime in.
