I am for gun control, for limiting certain types of weapons and the capacity of gun magazines. I am also for the regulation of other personal weapons and explosives. The coverage I saw said that he had a rifle, a shotgun and two handguns. We can't really ever ban shotguns or rifles in a place with as much wilderness and ranch land as Colorado. So how would gun regulation have helped here? He three smoke canisters and shot people in the confusion. If he had thrown smoke then gasoline in burning bottles he might still have killed and injured as many.

In a free society it is almost impossible to stop a crazy person who is willing to sacrifice himself.
