It's not a crisis of faith, nor an epiphany, and I haven't recanted yet, Thorne. I am simply questioning my position in the light of information I was previously unaware of, and, to be honest, am having difficulty accepting.
You say that a "well-armed and well-trained citizenry" would do more good than anything else. But what about a well-armed but poorly-trained citizenry? Are you advocating another law like the one in the C16th suppressing the playing of cricket in favour of compulsory target practice on the village green? What's the American experience here?
(In fact, it was necessary for that law to absolve archers from the crime of murder if they killed someone during archery practice! Would it be necessary to have a modern law making a similar provision?)
I wonder if crime in America has fallen in areas where concealed weapons can be carried because the criminals fear their "marks" could be dangerously incompetent gunmen. Or does that not matter, because crime has fallen and the end justifies the means?
