Who's behind the Anti-Knife Campaign?
Most sane people will look at the knife-control campaign as due to either hoplophobes or control freaks. There's another group that might support knife control: labor unions.
If knife control laws are passed, they won't ban all knives. If you need a watermelon sliced, you can take it to a licensed, regulated (and, of course, unionized) slicing shop. Everybody knows we need to license anything dangerous…
I earlier discussed knife control here.
