I'm just saying that if a cop had done this, he would be facing charges.
Cops are (rightly) held to higher standards than 12 year old girls alone in their home with an intruder.
In principle.
Fair point.
My understanding is that I could shoot only to stop an attack that could reasonably said to be an attack on my life. In court you will need to show how your life was in danger. In some states just breaking in is enough, in other states it is not.
If you keep a gun for protection you should be practicing shooting monthly at the least. You should mark out your firring positions and know what is behind them. If you do these things an attacker has little chance. They will be in an unknown place facing unknown forces. And don't hide. Hiding moves you to a crappy position, make the other guy try to hide. Lastly, don't show your gun or threaten them with it. It is for killing, not tough talk. If you need the gun, yell surprise!! and don't stop shooting until the attacker is done for.
