If the NRA was clever they would make a much bigger deal about how many guns are already out in circulation in America, and how there's literally nothing that can ever be done to remove them all. The vanguard of gun violence prevention's focus on keeping guns out of the hands of America's growing population of violent mentally ill individuals isn't realistic. It's going to be much easier to identify and remove the violent mentally ill people from society than to remove all of the ways in which they can inflict harm.
