Nancy Lanza could have afforded that insurance. William Spengler got his Bushmaster rifle despite being a registered felon and paroled murderer. The psycho murderer in Aurora, Colorado probably would have found a way. It will probably do more to deprive law abiding middle class and poor gun owners of the ability to get guns for self defense. What happens if you buy a gun and then can't or won't pay the insurance. Do they come and confiscate your gun? And what happens and who gets the money if the insurance pays off? What conditions does the insurance pay off on? Whose insurable interest is involved? How is it supposed to stop mass shootings like Lanza?
