More shootings.

[Autumnlicious]

If the UK didn't have such stringent hand gun laws they might have rates approaching our own. Surely you don't think it is their oppressive gun laws which accounts for greater murderous rage than in Switzerland. Commonsense tells us that the availability of guns will lead to more impulsive murders than other weapons. No one ever went on a mass murder rampage with a knife or blunt object.

Incorrect. Looking at the history of rampages under different locales, both guns and knives appear.

China has a tendency of people attempting to knife school children, for example.

The only good use of an example of using knives is that people can more probably swarm and defend themselves as a group.

Gun/Projectile wielding attempted mass killers have a much lower chance of being stopped with a human wave attack (swarming) and can attempt to murder multiple targets in quick succession.

Melee weapons requires one to physically charge and get within close proximity of a potential victim.

So, please, never say never. ("No one ever")

Point out the inefficiencies, the differences in chances of successfully escaping a melee weapon owner than a projectile (usually guns) throwing attacker, etc

Anyone can kill, the only difference is the chances of success, the chances of escaping, the effort exerted.
