Makes me want to call my insurance agent and check whether my liability protection would come into play for a defensive shooting.
I can answer that.
Not if you hit the person you intended to stop and no one else.
Liability Insurance covers injury to others that you cause by accident or negligence. Like someone slips on your steps, someone falls in your pool, or your dog bites someone (Beware of Dog signs don't protect you legally).
Liability Insurance will not cover someone else if you intentionally shoot them. No different than if you drove you car into the ocean and filed a claim. Intentional acts not covered.
Then there's the "who's covered" aspect. Liability implies your insurance pays someone other than you. You cause a car crash, liability coverage, which is mandatory, pays for the other driver's damages. IF you have comprehensive (collision) coverage, they cover your damages, too, if it's your fault.
So, in the case of you shooting someone in self defense, who would they pay? Not the person you shot, because it's not a "liability" claim -- the injury was intentional. Not you, because they'd be paying the policy holder for an intentional act -- something insurance companies spend lots of money investigating every year to avoid doing. Think arson...
This is why requiring gun owner insurance is such a farce. The people calling for these laws don't get these facts. They think you, as a danger to others, should have insurance that they, as potential victims, can file a claim to cover their loses. Basically, you own a gun, you kill 10 people at work, the families of the victims get paid through insurance. Easier than suing a shooter that commits suicide or dies from a Cop's bullet, right? Only if the Insurance companies lose their minds and write policies for this.
I have heard of someone shooting and missing the first shot when their front door was kicked down. That shot hit the neighbor's house across the street. Homeowner's Liability coverage paid for the repairs. Luckily, no one there was injured. That was accidental damage, though.
None of this covers you for legal fees, lost work, replacing a gun taken as evidence, etc. That's what the Gun Owner's Insurance policies do such as USCCA.
