And I'm asking a) what the relevance of the question is and b) why you're trying to play down the badness of a murder.
There are two sides that most people seem to take in regard to this law.
A) "good" officer busts into "bad" guy's apartment, who then shoots and uses this law as an excuse.
B) "bad" officer busts into "good" guy's apartment for whatever reason and the guy ends up dead. Nothing happens to the officer.
Don't take these scenarios literally. I assign no particular meaning to good and bad. Everyone has their own interpretation. The outcomes of each scenario are arbitrary, but when people argue, scenario A always goes bad for the officer and scenario B always goes bad for the citizen.
It's about choice to me. Everyone in the two scenarios has choice, except for the dead guy in scenario B. The "good" officer in scenario A chooses to uphold the law to the best of his ability. The "bad" guy in the same scenario chooses to shoot. The officer in B chooses to break into a house on unlawful grounds.
The guy who dies in scenario B gets no choice. He dies. Without this law, if he responds by shooting the threat, he gets life in prison or the death penalty, both much more than if he, for instance, shot some stranger on the street. He still dies. Why is that more okay than scenario A to anyone? It doesn't need to be repeated that killing is bad, but why is it that it's more okay when innocent citizens get killed? If you can't see how this question is relevant, I'm done explaining. Believe whatever you want, not like it matters to me.
As for why I'm trying to play down the badness of a murder, where did I do that? I said that I'm willing to do it to keep some jackass who's high on power out of my house. Here's a question for you, then. Cop busts into your house unannounced. He refuses to identify himself or produce legal documentation. Your little anklebiter of a dog yips a little bit at the intruder and is shot in front of your kids (it's okay, it was a vicious animal that was obviously going to attack him). You can either A) get beat up (Who's to say you weren't resisting? The court will believe him over you, your wife, or your children) , drug out to his car, and charged with whatever, or B) shoot him. What do?
It's happened before. It will happen again. You haven't heard about it? Take a look at the news. To me, the choice is obvious.
