Whats funny is the anti's called it "murder insurance". Now they want it required.
Most people (anti-gun Liberal nut jobs) have no clue how insurance works, nor who would benefit from it if someone actually used their firearm for LEGAL self defense or defense of others.
They believe if you own a gun and use it to kill or injure someone, the victim or their relatives would get money.
Nope. Insurance won't pay in the case of intentional criminal acts. Otherwise, you could shoot your wife to collect the insurance. Now, if she was threatening your life, you'd get money to hire a lawyer to defend you in court and possibly replace lost income and a confiscated firearm.
If they want everyone to have LIABILITY insurance similar to cars, take a look at how that worked out. Uninsured and underinsured protection is now required because people are driving with no liability coverage.
Worst thing -- there's no national registry, and most states have no state gun registry. How do you force people to buy insurance for the privilege of owning firearms? Are you going to track ammo sales to locate unregistered & uninsured gun owners?
The entire concept of forced liability insurance for owning guns is whack.

What other Constitutional right requires insurance in case you decide to misuse or abuse it?
I think we need voter insurance. if you elect someone like Biden, the insurance company needs to send the ones who voted for Trump a big check.
