Just another dumb Plod on a horse
Toy 'guns' have been with us since 1865, as gun manufacturers suffered business challenges after the US 'Civil War' and found success, after making a few changes to their factories and began to build cap guns instead.
Canada, as another poster wrote, has extremely stiff gun laws (even bows and arrows) but these less than smart horse riders should know that 'coloured' guns are restricted and therefore anything resembling a gun, especially those with a 10 cm tip of orange colour, is easily discernible.
Canada doesn't have 'carry' laws either - and it is extremely unusual to see a real gun on the streets other than those used by our Plod. Security guards very occasionally have gun permits but most of their weapons are actually chemical types (gas or liquid). Canadian society shares much in common with the USA and proves that culture affects the use of weapons.
Cops with guns doesn't equate with killing civilians. The Chinese police carry guns as do many of the police in Laos, Kampuchea (Cambodia) and VietNam but their use is very infrequent. There has been ONE case of a police gun being used in VietNam this year (on civilians) and that was to stop a robber escaping on a motorcycle in SaiGon/Ho Chi Minh City. In VietNam we are even unable to buy matches (think pipe bombs) and sparklers have only been available for two years.
Given Cameron's 'Nanny Society' it's surprising even 'cap guns' are permitted. I was taught in the British Army how to make very effective explosives from the contents of the average UK kitchen. In fact, an ordinary light-bulb plus one other common household fluid will effectively 'clear' an average-sized room, as our training sergeant proved.
