Great response! It should be pointed out that this particular shooter had his apartment wired with very sophisticated explosives so if guns were not available he could easily have purchased a ticket, taken a seat in the theatre, stowed a backpack under his seat, left the theatre, and a few minutes later the bomb in the backpack explode and kill perhaps even more people. Look at what just happened in Bulgaria when a bomb on a bus killed 7 and injured 20 more. Guns are not the problem, sick people are the problem. This guy had no history of violence and would have passed a background check with flying colors. The only thing that might have stopped or at least mitigated this rampage is if someone had shot him and stopped it.
