Yes, if he wasn't being an immediate public nuisance, then the police shouldn't have broke in. But two dead cops for this error is extreme.
A "complaint" in and of itself does not mean a law was being broken, or had been broken.
It's against the law to disturb the peace.
In college I had a party one evening in my apartment. Some very studious neighbors called the campus police who knocked on my door. I saw them through the peep hole and talked to them through the door. They said there was a noise complaint. I asked what time it was, and assured them the music would go off before 10 p.m. - which it did. They hung around for a while, but there wasn't much they could do - I was within my rights too!
You have no respect for others.
This guy was just a murderer ... IF his acts were premeditated; IF the police acted within the law, and ;IF he had the capacity to make a rationale judgment, you may be right. Thanks for the discussion.
He's a murderer.
Sure I have respect. I refrained from puking up beer on their front doorstep!
