Cracked has an article about UK policing.
Which goes about as well as you think.
Amusing that #2 is a "Oh sure we have thousands of armed cops in London, but there's no armed cops!"
And a lot of the article is ignoring how rare US police use their weapons.
Or that people in the UK can own some guns. But hey, handguns are banned.
Also...... in the comments.
Here's a hint. If the article is about a "kinder, gentler and deescalating" form of policing when someone asks "well how would they ban guns in the US?" maybe you shouldn't go "They'll send the Army after gun owners."
