My bro told me a cool story yesterday that a workmate told him:

His friend (person who told the story) was waiting at a bus stop late when a group of 6 townie inbreds (3 blokes, 3 "girls") came and started asking him about who he was, how old he was, where he lived, etc. Suddenly the one doing the talking came close to him all like "gimme your money, gimme your money mate, what? Gimme your money".
My bro's mate looked at him calmly and said "seriously mate, don't bother".
"what, what the fuck you on about? gimme your wallet!"
"I've got a knife."
Pikey stares at him for a couple seconds and just says "yeah, safe mate, safe." and they all walk off.

My bro's friend didn't have a knife for shit but they still shat bricks. It just shows the comparison between the UK and US. The most dangerous thing you can be confronted with here in the majority of muggings is a knife. In America, it's a gun. Consider our much lower rate of gun-related deaths and murders and you'll find it's not really that hard to comprehend.

Anyone that wants to make a government conspiracy theory out of it is just a dumbarse.
