Once more proving that “Gun Control” is a myth.
Piss off enough people, or just one very determined enemy, and a weapon will be found or made.
Would the anti-RKBA types be happier if this was done with a IED that killed dozens?
Maybe a Petrol or Propane bomb would please them?
Even a simple can of hair-spray can be used to kill.
Perhaps an old sword as used in 1960, poisoned Shuriken, Archery, Spear, Cross-bow, or some other traditional Japanese weapons would make it all OK?
Murder is murder no matter how it is accomplished.
Most assassins used blades in Japan, though guns are catching up.
