Their assumptions are totally faulty. They believe that if you remove the tools for committing violence that people will not be violent. However we know this to be false - even if people are reduced to throwing rocks, violence is still possible. With an illegal guns trade, it is even more possible. All the regulations do is prevent potential victims from defending themselves.
It all goes back to the left wing assumption that man in a state of nature is good. No.

What criminal actually needs a gun in Britain? They can do most of their criminalizing with just a knife now. Sheesh. You'd think the Thug Party is in charge.
