From Joe Huffman over at the View From North Central Idaho comes an interesting question:
Can you demonstrate one time or place, throughout all history, where the average person was made safer by restricting access to handheld weapons?
Several have tried (mostly the anti-freedom/citizen disarmament set) to answer it, and have failed miserably. What they cannot get their minds around is this. That when the .gov has the monopoly of force, there is no limit to what they can extort from the populace as a whole. I find it ironic that the very folks who eschewed "the Man" when they were in college now see fit to turn themselves into "the Man". The very same people who will hold a picket sign demanding "keep your laws off my body and your government out my bedroom" have no qualms at all with having armed agents of the state provoke a violent encounter with non-violent people doing things that non-violent consenting adults do.
What this all boils down to is, in response to the question posed above, they can't.
