I think linking mental health evaluations and admissions to mental health facilities to back ground checks, adding background checks to gun shows, better training for CC permits (such as requiring Utah CC carriers to take a shooting course each time they renew), adding an armed guard or two to schools (not advocating armed teachers) and removing gun free zones at movie theaters, malls, parks, zoos... will do far more towards lowering gun violence.
I'm asking again, which of the recent mass shootings would have been prevented by linking mental health evaluations to background checks?
I agree on adding checks for gun shows and better training.
I don't think armed guards will make schools or other areas safer. Most of these mass shooters expect to die.
