On the surface, to the uninformed, this sounds great !!!! But think about it. If you or yours is the victim of a bogus shooting, and some politically connected shooterhas a judge in their pocket, rules a totally bogus shooting is "justified," you have no civil recourse.
What's needed is not MORE laws, but honest judges. Let someone file a bogus lawsuit against a citizen. First time it gets to court, BAM !!!! Out the door it goes. Basically, what the NRA (negotiate rights away) has done is deprive potential litigants of due process, a VERY dangerous concept, something embraced by Amerikans. Change the culture of Amerika? Absolutely. For the worse. If the NRA wants to do something constructive, let them restore the rights LOST due to their involvement.
