I'm sorry but I don't think this is something to be solved (primarily) with technology. Until as a society, we stop utilizing guns as a cultural norm (by this I mean the use of arms for all purposes not just ownership by private citizens), all tech is going to do is at best slow down the use of weapons, to the point where they are effectively useless or make it such that only criminals have easy access to weapons. I strongly believe in guns don't kill people, bad people with guns kill people.
