There is no doubt that we have a real problem about what to do with armed criminals.
Is it too simplistic to say: Get rid of guns!!! Make it illegal to own them, or use them unless you are licensed, trained, and using them in a full-controlled environment.
Is it all too-simplistic to say the same thing abotu knives also?

The Taser (and there are a number of variants) has a basic problem...and that is that you use it like a gun.
It does nothing to diminish gun violence, and may even provoke it, if we say that you point a gun at someone who is pointing a gun at you.
Most of us here are deeply disturbed by what happens in the US. Less guns seems better than more.
This is a bit of a ramble...but you get the point!
