This is the usual course of events. First the police have to determine if the shooting was justified from a criminal perspective. If you get an "all clear", you still face round two. Round two is a civil suit by the person shot or surviving family members. A civil suit only takes a "preponderance of evidence". When you pull the trigger to defend your life, you can expect a minimum of $75,000 in legal expenses to follow. That's if everything goes your way.

I wonder if there is an insurance policy that would cover that specifically. I doubt it, but if it was setup right, the premiums would be low. I think the NRA offers something along these lines?
