Licensing and training will do NOTHING to reduce either gun related crimes or violent crimes. Safety's that only operate when used by the owner are not realistic.
Are you guys really trying to make a difference or just piss off the right-wing gun owners? Bans do nothing and you won't be successful. If you guys really want to do something that will make a real difference, think of something that will keep shit-stains like this from getting their hands on a gun:
Whatever you are proposing, if it would not prevent crimes like this you are only making noise. Keep in mind there are MILLIONS of guns already in circulation. Register them you say? Bullshit. Crimes will be committed with unregistered guns that were traded on the black market. Confiscate them? Good luck, that will drive every fringe group to declare war. Oklahoma city bombing anyone?
Why don't we make being in a gang illegal? If you crack down on gangs you will stop a lot of the gun violence. Let them duke it out and shank each other in prison riots and not the streets and neighborhoods we live in. Legalize more drugs, the drug trade drives most gun violence. I have no problem voting for and funding these things as they will actually work and tax revenue from drug sales can fund the gang prisons we'll need.
