Ask just about any person in my country and they'll ask the same thing: Why oh why can't you Americans so much as regulate the *categories* of guns? (And then I'd be bombarded by pro-guns people telling me "it's because the citizens also need to protect themselves from the government" whilst at the same time telling me that "The United States armed forces would sooner cut their balls off than point their guns at the people they'd sworn to defend".) Slippery Slope? How 'bout "possessing the proverbial cattle-slaughtering weaponry when you needn't do anything further than killing a hen" escalation slippery slope?!
