Sorry to disappoint you, but the UK, with some of the worlds' most stringent gun control laws, also has one of the lowest rates of gun crime. Because gun control legislation isn't just about who can own guns, what guns they can own and how they store them. It's also about strict controls on manufacture, commercial storage and imports. It's as difficult here to get hold of guns illegally as it is to buy them legally. Also our police Armed Response Units are far more efficient at containing and de-escalating incidents than US SWAT teams appear to be.
