I'd like to think they'd have a hard time finding enough cops or soldiers to do this nation wide. To say it would not be pretty would be a gross under-statement.
Once the last of that blood had been washed from the street and it was decided that knives should be confiscated, I'd like to know how they'd propose getting rid of all of those since there are no doubt an even larger amount of knives present in the country.
This excerpt in particular made me chortle:
"It would have to be the case that the term "hunting weapon" did not include anti-tank ordnance, assault weapons, rocket-propelled grenade launchers, or other weapons of war."
Since he doesn't qualify his statement, maybe he means every war which in that case, bans even muzzle loaders. I can be ridiculous too.
