Guns. Why?

I've come to the conclusion that people who want to use guns will get them through legal or illegal means no matter what. I think the best way to reduce gun violence is to create a society where people are not forced into a situation where they believe they need to have a gun; either to protect themselves from harm, to threaten/shoot other people in order to get what they want.

My ideal society, as described on this blog, would have plenty of preventative technologies (metal detectors, scanners, etc.) in public buildings, and at the entrances to cities, in order to control the flow of guns and other materials used in crime into the city. Law enforcement officials may not necessarily even have guns, although they could have some sort of non-lethal armament, that would be designed to subdue would-be criminals rather than injure or kill outright. The jury seems to be out on tasers at the moment, but I am sure there are other technologies that are just as effective (rubber bullets, sonic weaponry, etc.)

There are still people who are ideologically driven to commit violent acts, and others who have mental disorders who will attempt to commit acts of violence. I think that the people with mental disorders should receive treatment rather than receive punishment. The ideologues who wish to force their views of how the world should be through violent means should simply not be allowed to enter the city.

My ideas surely aren't perfect, but those are my proposals. I'd like to hear other peoples' opinions.
