It is quite funny how weapons can be banned, when the prime function of weapons are to kill people. Very very very ironic, and dumb.
Would you have flame throwers, land mines, nerve gases back in common use? Even weapons of war have some degree of humanity to them in their design.
If you shoot someone in the right place you can kill them with pretty much any weapon, from a catapult upwards, making every shot potentially fatal with expanding or fragmenting bullets seems pretty dark to me.
