Chances are there aren’t many insurance companies you could buy a policy from.
Ok, so lets assume for the moment that such insurance were available, and mandatory.
Further, were I to shoot someone who was “trespassing against me” to use a biblical term. It would be in my interest to make certain that the offender did not survive such an encounter lest he sue me, and my insurance would make him and his relatives “lottery winners”. Further you could see them making it a “no fault” type of policy which pays no matter what.
I say to these ass clowns...legislate away. I will not comply, period.
