Get rid of guns, and the murder rate WILL fall, I promise you. Let guns be freely available to anyone who wants them - including, now, convicted killers and lunatics, and more people will be murdered, and more people will die through accidental shootings.
Tell that to those countries who have tried your suggestions. Try convincing them that you are right and the statistics kept since guns were outlawed are incorrect.
That is bullshit rhetoric and I'm, glad most people see through it.
