I read posts here stating that perhaps there should be security guards at movie theaters, or perhaps the movie company should have thought about a better premiere time, or why didn't his purchase of weapons and ammunition trigger some red flags, or why wasn't someone else packing heat in the theater. Some theaters have security guards, some don't. Some theaters can't afford them. But even if we had security guards at theaters, could a security guard have stopped this? And what is the next venue where we need security guards? Ice cream shops? Grocery stores? The doctor's office? This event can occur anywhere. As far as premiere time, the movie company is going to have the premiere at the time when they think they can garner the most viewers and publicity. That is American free speech and capitalism at work. There is no way they could have anticipated this event. As far as the purchase of weapons and ammunition in large quantities, why would that trigger any red flags? This is our American 2nd Amendment at work. There is no legislation to track ammunition purchases at the federal level, and none at the state level of which I am aware. The federal government does not track gun purchases once the purchase is cleared, and not all purchases are even cleared. Private sales are not all cleared by the federal government. The gun is not required to be registered at the federal level, although I am not sure if Colorado has a registration requirement. In any event, registration would make no difference. That only helps track the gun after a crime is committed. If someone else had been packing heat in the theater, that person would have been able to do nothing. That person would not even get a shot off in a darkened theater with tear gas and facing someone with an assault weapon. There is no effective way to halt all random acts of violence. Random acts of violence will continue to happen from time to time, and when they do people get up in arms for a day or two, then everyone's life goes back to normal--except the lives of those who were killed, and their family members. We have freedoms in America--there are up and down sides to the First Amendment, the Second Amendment, and the rest of our constitution.
