Repeal the Protection of Lawful Commerce in Arms Act. Preventing gun manufacturers and dealers from being sued? Why does Big Government has to interfere with free commerce? Repeal this Act and let the people decide! Let the families of all the victims in this country go after them. Additionally, close the gun show loophole, make a bill that if you sell more than one gun every five years, you are, in fact, a dealer.
If you open the floodgates, and let the people go after the arms manufactures, there is no need, for now, to amend again the 2nd amendment or attempt any kind of gun legislation.
Nor should we get distracted from the issue. Guns are the matter. The NRA and its followers use all kind of subterfuges to just gain time. Their strategy is to give up small steps using subterfuges to derail the real issue: guns. It may take many, many years, but at the end, the people will prevail and they know it.
