The good news is that they weren’t shot with a firearm thanks to gun confiscation, right mates? However rogue knives roaming our streets can be just as dangerous as rogue guns are. Damn inanimate objects going around killing human beings.
Knives are more dangerous. You never run out of ammo, and they can be used from multiple angles of slashing and stabbing. A gun can only be used in the direction the barrel is pointing. If you know how to throw, some knives can be used to attack at a short distance. Altogether, a superior weapon to guns in the hands of a skilled man. But getting back to your joke, next shoelaces will go around garroting people.
