Protection of Lawful Commerce in Arms Act, gun crime and focus [View all]
https://en.wikipedia.org/wiki/Protection_of_Lawful_Commerce_in_Arms_Act
The act was passed by the U.S. Senate on July 29, 2005, by a vote of 65-31. On October 20, 2005, it was passed by the House of Representatives 283 in favor and 144 opposed.
The final bill passed only after adding an amendment that mandated safety locks on handguns, and after preventing the renewal of the assault weapons ban from being added.
There have been lawsuits brought against manufacturers and dealers in guns by victims of gun related violence and by municipalities. Some suits (Badger Guns, for example) were well founded and resulted in a verdict against a seller. Those suits against businesses that have broken no laws have been and should be dismissed.
For 2014 the FBI reports 68% of firearm homicides involved a handgun. Only 3% involved a rifle.

In the US, 16 states require a background check on all sales of handguns. This applies to
ALL sales from licensed FFLs to sales between next door neighbors, classified ads, internet and gun shows.

I suggest that, if you live in one of the other 34 states and you spend your time advocating for another national assault weapon ban or pushing for the repeal of the PLCAA, your efforts have the wrong focus.
