What is concerning is the attacks against foreigners for no reason other than say taking a photo with a chinese girl. The overall murder rate may well be lower than the USA, that still does not mean China is any safer. The amount of attacks may well be higher, saw a guy get stabbed in the back with a broken piece of metal piping on the street in broad daylight in Shenzhen, in the USA there is gun crime, in China there are people who will use bats/knifes/meat cleavers/pipes.
