Rick Perry: Arm Moviegoers to Prevent Shootings

Republican presidential candidate Rick Perry says better enforcement of existing laws would have prevented the Louisiana movie theater shooter from buying the weapon he used to kill two people and injure 9 others, but he also believes allowing people who have proper training and permits to bring their guns into such places could reduce the loss of life.

"I believe that, with all my heart, that if you have the citizens who are well trained, and particularly in these places that are considered to be gun-free zones, that we can stop that type of activity, or stop it before there's as many people that are impacted as what we saw in Lafayette," Perry said Sunday on CNN's "State of the Union."

John Russell "Rusty" Houser also fatally shot himself. He had a history of mental illness, including an involuntary commitment to a mental health facility.
