"It's too hard to enforce" isn't an excuse. People are dying.
That's the argument for prohibition too.
Correct me if I'm wrong, but isn't prohibition like.... an actual prohibition? As in a ban? That's not the same argument, since nobody is arguing for a ban on guns. It would, however, be the same argument as increasing the drinking age from 18 to 21, creating stiffer penalties for DUIs, making bartenders legally responsible for serving intoxicated patrons, etc. etc. etc.
Guess what? I'm sure you already know, but the number of DUIs and drunken vehicular homicides has dropped precipitously since the 70's.
What we did was we saw a problem, we took actions towards the problem, and we improved upon the problem.
What we didn't do was say, "Well we need to be able to get sh#t faced drunk at all times". What we didn't do was say, "This isn't an alcohol problem, it's a people problem." What we didn't do was turn down any possible legislation because there's no PROOF that it will work and we didn't know how it would be enforced.
I mean, is the argument here that we'll just let X number of people die because I'm too lazy to reload more often? What's the argument? Why do you need clips that hold more than 10 rounds, or five rounds? What are you doing that you need to carry 30 rounds in a magazine?
Why do you need more than one beer? Why do you need more than 150hp in a vehicle? Why do you need to drive faster than 55 mph?
C'mon man.
You're defeating yourself here. Knapp's entire point is that we don't NEED guns, we WANT them.
And you are supporting his argument. Because we DON'T need more than one beer, 150hp in a vehicle, or to drive faster than 55mph. We want to do those things, and while people do die from those sorts of things, we've taken a lot of steps towards trying to limit the amount of damage, especially to innocent parties, for people who do those things, and none of those things were invented or designed with the sole purpose of efficiently taking lives.
