That is individual choice as it should be.Self defense is an individual responsibility, as soon as people learn not to count on us who do carry, and the police the better. Not everybody should carry, or want to, but don't expect me to stick my neck out for you.
But a honest question
If every armed citizen takes the "me and mine only" stance, will it not wind being that active shooters, are never challenged during their slaughter?
Police don't figure in the equation. They are rarely there when active shooters,strike and even more rarely will act to stop the shooter in time to make any difference.
