The point at issue, viz., "gun control" - by which I really mean the elimination of such weapons in private hands - is, I believe, entirely achievable over time, given much determination (even though Haim and his cohorts and consorts will most likely consider this to be 'unacceptable social engineering').
I thought the issue was to reduce violence. You haven't made the connection. I think Gary has made the connection, but he forgets. Your logic reminds me of the the gnomes in a South Park episode describing their plan to make money by collecting underpants...
PS: I know you won't get this, but the others will, including Gary.
