We are talking about restricting access to guns. The mentally ill shouldn't be stockpiling guns/ammo/body armour legally. That is the problem people want to take care of. Restricting access for those who shouldn't have it is not something that will effect the average responsible gun owner just as it doesn't here. If you want a gun you need to go through the vetting process. The problem lies in the fact that many gun owners in the states are some of the most paranoid people around. The government isn't coming for your guns. They want to prevent those who should never handle a weapon from doing so easily and legally.
Why does a citizen need a 30 plus round magazine? who are you going to war with?
That's a fallacy- they have 300 million guns already, what possible cure is there now?
Instead of wasting all this energy and money on a fight over gun control, they should re-think their approach to dealing with troubled youths, bullying, and especially mental illness... which is the underlying cause of almost all of these massacres. Why in the world is this much energy being expended on the WEAPON instead of the CAUSE?
