These are the reasons the Castle Doctrine or Stand your ground exist.
This is another case where being protected and killing someone in self defense is the only option. It also proves that the police DO NOT STOP CRIMES most of the time! They arrive AFTER A CRIME HAS BEEN COMITTED IN ORDER TO INVESTIGATE.
If you are a victim would you rather be beaten, robbed, raped killed or your children killed and if you live let the police investigate and hope they find the perps OR would you rather have a CONSTITUTINALLY PROTECTED weapon, be trained to use it and stop the attack before you or anyone else is harmed or killed?
