However, he might have been caught making an illegal purchase, IF THE PURCHASES HAD BEEN ILLEGAL. All of this is very hypothetical, and we can all dream up "what-if" responses to defend our cases. My argument is for laws that would tend to reduce such incidents and their lethality. The fact that this particular nut also knew how to boobytrap his apartment with bombs does not mean that every nut would have necessarily committed mass murder by other means than the one chosen. That is not an argument for keeping assault weapons and high-capacity magazines legal. They should be outlawed in the same way that bombs are.
Rubbish. The fact that we manufacture a massive number of guns to feed the violence is a factor. That's why the Mexican drug cartels like to shop in Arizona. Another factor is that we have no uniform laws to impede the flow of guns across internal political borders, which is why most guns used by criminals in Washington DC come from legal purchases in Virginia. Our problem with guns is not caused by geography and physical location. It is caused by our myopic approach to the availability of guns.
False analogy. Drugs and guns pose different threats to society and require different social policies to deal with them. Nobody is going to injure over 70 people in just a few minutes with a bag of weed.
OK, let's just stop right there. This is not about you. I don't know why you feel you need all those weapons, but maybe you haven't felt any need to use them yet. Tomorrow, who knows? Nobody volunteers to go crazy. There was probably a time in the life of Mr. Holmes when he didn't desire to slaughter scores of people in a crowded movie theater. The point is that he could prepare for such a moment without violating any laws at all.
Yes, we do need to improve our public policies on the treatment of mental health. That is a completely separate issue from whether we need to curtail the availability of weapons of mass destruction to those people who don't get treated in a timely fashion.
Here's the thing that our pro-gun friends just don't get. What if the police had known about the Holmes arsenal before he committed himself? Could they have done anything about it? Yes, if they knew that he possessed bombs. No, if they just knew that he possessed guns, ammo, and high-capacity magazines. Collectors of assault rifles may think it unfair to make them give up their gun collections. I think it unfair for those people in the movie theater to have given up their lives so that gun collectors can enjoy their collections of usable assault weapons.
