By the way, with respect to the kind of acrimony we can expect, I suggest folks go back and re-read this thread:
Ryan Frederick's Case, Chesapeake
There was one guy who posted something about how he did "lawful" home invasion raids as a law enforcement officer and that's why he's an expert on the subject. No explanation as to why he thought they were "lawful" other than the fact that he had a warrant. That would get him out of civil liability under 42 USC 1983, but it should not save him from being shot when he bursts in unannounced.
I'm convinced that Ryan Frederick was railroaded and that took a plea deal when he should have won at trial. I'm still trying to find out about the lawyer he had at the time. All I can tell so far is that he's a good marketeer.
The situation Ryan Frederick was in is almost exactly the same set of facts as represented in the 1604 English case that first used the phrase, "castle doctrine": "A man's home is his castle, and he has as much right to defend his home as the king has to defend his castle." That case has been cited repeatedly in Virginia opinions and is the basis of the "knock-and-announce" legal principle. It has never been revoked by act of the legislature.
I expect this to be the cause of the most serious opposition to enactment of a real castle doctrine statute, because the right to defend the home is the heart of the castle doctrine, but there are people who think that unlawful home invasions are a necessary part of law enforcement, and there are judges who will side with those people, regardless of what the law says. That was the reason The Honorable Ken gave me for why a statute was necessary, btw.
"And the second is like unto it:" there are people who do not want us to have any valid defense against a criminal charge arising out of defensive shootings in the home. I suspect this is precisely why the half-dozen so-called "castle doctrine" bills introduced recently were worded the way they were.
