Did SWAT make entry to the house or did they work on a peaceful solution to the problem? I don't think the article says anything about a shoot out. Just saying....
From my perspective, I wouldn't want to just walk up to the door and ask a guy, who may or may not be a little off reservation, if he would mind fixing his neighbor's siding since he blew a slug through it. Even as a cop, if someone launches a round at my house I'm grabbing my wife, kid, and carbine and calling it in!
I understand the sentiment if wanting to preserve rights... I get it. However, LE isn't going to ignore a call for help (which existed here, this was not police initiated) and they are certainly not going to show up unprepared for the worst. All I see in the article is "guy goes a little crazy, shoots at neighbor's house, barricades himself and eventually surrenders."
Some of these posters really should step back a minute and look a both sides of the situation (not story) as it stood at the scene. And perhaps do a little reading on MGLs regarding assault and felony rights of arrest. *off soapbox*
