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.
- 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?
As a citizen with a gun I can shoot you before the police arrive.
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.
