It is possible the explosions the homeowner heard were flash bangs and after that it would not matter how loudly they scream law enforcement upon entering the home the homeowner is not likely to have heard it.
How many of us have any idea of what a flash bang is in the first place. The female in the home is pregnant, if her boyfriend were not at home or the cops got the wrong address, in the middle of the night get invaded in ones home, Grab a gun and fire it is just human nature.
This home owner was just protecting himself, girlfriend and their baby. I can not give a damn if this homeowner is a felon or a car thief, he has the right to defend himself and family from unknown danger.
This crap about not allowing suspects to destroy evidence is funny, just try flushing a 3 foot pot plant down the toilet.
The No Knock law that is dangerous, two many people have died both civilians and police have died because of it as I looked into it.
I know the terror of having a warrant to search my home and confiscates my poor old PC.I got it back in 3 weeks but I had bought a new one and did not give a rats Ass if the old one was returned. I was more concerned on how anyone could get into my PC and use it to defraud others. Never did know how this happened, but fortunately the police came in the day time and did knock on the door.
Had the police come at night when hubby was Bowling and kicked in the door, things may have taken a very nasty turn.
