That's a simplistic way of looking at it.
Of course it is. It was a quick response, not a detailed outline of what I would envision as comprehensive gun reform.
Of course there are shootings on military bases. Performed by trained soldiers with mental illness. School shootings are mostly perpetrated by kids with mental illness. There's a good chance that armed security will deter an armed kid.
There's an even better chance that reducing the amount of available firearms and better regulating those that remain available would deter school shootings altogether. Don't need "deter an armed kid" if they can't become armed in the first place.
As darkknight pointed out, most mass shootings are not perpetrated by people with a history of mental illness. Mental illness certainly needs to be addressed in the US, but mental illness is not the core issue with gun violence. The core issue is the overt saturation of firearms and their availability to the public.
How would you remove/regulate firearms?
Much of what adjl noted, though I will add that all firearms should be insured, like automobiles. There should be a limit to the number of firearms a person/household can own. No one should be able to amass a personal arsenal. Same with ammunition. A reasonable amount of ammunition for personal use. No one should have a stockpile of bullets where they could essentially murder thousands of people.
