criminals carry guns households carry guns to protect themselves from the criminals with guns.America is awash with guns. NRA all powerful lobby group love their guns.If several mass murders are not enough to change that attitude the vicious circle will just revolve seems strange to us but not Americans.who are we to judge
You only need to do a simple Google search, to see how many homicides take place in any major city, in the USA on a daily basis. So the odd massacre here or there isn't going to make much difference to the way some American's think.
Just fancy that happening here in the UK, and how the public would react, that the government was not doing enough, in protecting its people!.
The problem is, like I said earlier, its a knee jerk reaction based on speed, with very little consultation.
