hooleybooley: No offense mate, but those cases are dishonest comparisons to the situation to the US. Iraq had massive stockpiles of weapons which were left unguarded when Saddam was toppled. Somalia, to be kind, is in a state of anarchy. The Viet-Cong were being supplied by the NVA. The CCP confiscated weapons from warlords which effectively ruled china due to a weak central government. The American Revolution and the French Revolution took place at a time when warfighting was completely different to what it is today. None of these circumstances bear any resemblance to citizens spontaneously taking their own weapons and fighting a government.
The reason automatic firearms are banned from civilian ownership is that most people will panic in a stressful situation and start spraying at whoever's threatening them which in turn will cause even more injuries or deaths. The proliferation of firearms in the criminal fraternity in the US was probably in part influenced by the fact that so many civilians carried guns. It's simple escalation: if their victims are unarmed, they carried knives. When the victims started carrying knives, they carried pisols. When when victims start carrying pistols, they'll resort to carrying automatic weapons. What then? Everyone has to carry a Kalashnikov when they go down to the shops at night?
