Current technology, no, not a chance.
The theory posited in the other thread about a tazer type device which could be fired like a gun and was as effective and reliable? Absolutely, I would suggest that the reasonable, responsible, moral, law-abiding citizen would have the DUTY to use a tool that can effectively save their own life without taking the lives of others.
The caveat being that it would have to function essentially identical to a standard firearm, except that it would incapacitate instead of kill.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
