Like the freedom to go down-town without much risk of being beaten to a pulp by drunks, as in The UK.
This has happened to laowai who worked in China as well. You might be from a ghetto area of Britain. I have never been to your country but I am quite sure places like Chelsea are not filled with drunks or gangs wondering around.

I myself was assaulted by a drunk once at a train station in the state that I reside in. With that being said, the police were on to him in a matter of minutes after I reported the incident. A foreign teacher in China who is married to a Chinese woman happens to know a local Chinese police official who is a close friend of the woman. He has repeatedly asked the police to get involved with a case of pedophilia where a 14 year old girl was sexually assaulted by a Canadian man in his late 40's. He got the response supposedly that the police cannot do anything about things like that.

No society has ever gotten completely rid of things like poverty and crime. The better ones marginalize the criminals to the fringes. The worst ones let the criminals run the country for thousands of years!

I think that he has been reading the Daily Mail too much! Maybe he is quite a small lad that can't handle himself too.

I actually do come from one of the roughest areas of the U.K and although there are certain areas that you shouldn't walk around at night, I mostly feel ok as long as I keep an eye out. It is not even drunk adults that you have to worry about, it is the gangs of teenagers (some who are actually quite big and armed!) that need not fear any real consequences of the actions because they are too young to get a full prison sentence. They will tend to happily rob people just for a buzz, for cash or gang related reasons.

China admittedly, does feel safer but not as safe as it used to. There's more hostility to foreigners these days and the Chinese aren't really known to fight one on one.

Was that girl sexually assaulted as in a consensual statutory way or forcefully, against her will? I think if it was the latter, the Police would do something. If not, I think just sneakily informing a few slightly nationalist Chinese guys, even just the male students would do the trick.
