guns democratize mass murder. With a gun, I can kill a bunch of people before police can stop me. A knife? At best I can kill one or two in a public place before people run away and eventually a different group is going to stop me pretty quickly.
As a citizen with a gun I can shoot you before the police arrive.
- can you build bombs to blow up an apartment complex full of 1000s of people?
- can you poison the water supply of an apartment complex full of 1000s of people?
- can you drop a harmful substance using a $50 drone onto an open area where of 1000s of people have congregated?
Killers are going to kill. Guns don't democratize it, just makes it easier. Maybe at best YOU could kill one or two:

So they should stop you from 3d-printing knives too.
