THE GUN SHOP DIDN’T SMUGGLE THE GUN.
THE U.S. CITIZEN THAT BOUGHT THE GUN SMUGGLED THE GUN TO MESSICO.
I’m thinking that gunshop owners have been the biggest critics/sources of info on “project gunwalker”. But your right; not the SUV’s fault that someone got hurt, but the driver’s. Not the gunshop or the gun, but the purchaser or the gunman.
The only real solution is to hunt down the people responsible, followed by a swift trial and swift punishment.
Of course, the justice system has done nothing swift since the 1940’s, so I'm not holding my breath here.
