Ok,So I think rightly or wrongly Criminals have guns and law abiding citizens have none(for self defence).We don't need gatling guns and Rpgs! Just pistols and shotguns and perhaps some semi-auto carbines.The role of the armed responce is to RESPOND not to swoop in and drop criminals before they start slaughtering.Derrick Bird wouldn't of been such a disaster if a respectable Citizen just shot him.
As to the availability of guns Criminals saw down legal length shot guns and take deactivated firearms(legal) and drill out the barrel.Also just because guns are available won't nessisarilly cause more gun crime.
Of course prospective gun owners would need to take a gun safety course,creating jobs for injured servicemen and women.
