Of course, its not the law abiding citizens carrying guns we should be worried about. If a thief is trying to rob you and you pull out a shooter, he may very have one also, then it could be the good old, bad old wild wild west revisited ......not something us non tooled up bystanders want to be stuck in the middle of. As, the average Elmer Thud gun carrying ahole, can't shoot for toffee.
If, I ever get held up by a thief with a gun, knife, or sword (really?) then nothing on my personage is worth me ending in up hospital, or on a morticians slab.
Its about 200 years to late for gun legislation.
All we can do is be lucky, its a jungle out there......sadly.
