sixshot I beg to differ about crime in China. I've been living here for a little over 6 months and for the most part I've found it to be extremely safe. Pickpockets are everywhere, and from my understanding pickpocketing etc is far worse in big cities in Europe, USA, and Aus.
I agree that in Guangzhou, Shanghai, Xi'an, Beijing and Shenzhen pickpocketing etc is more common than other parts of China as there are more tourists. The punishment, however, for robbing someone (in particular a foreigner) will be extremely severe. As I'm sure most would know, plenty of people have been executed for less.
You are right though that it's important to be careful in crowded places. Keep in mind that although the punishment is severe the type of person that will rob you might be working for 20rmb per day (2 euros or about $2.50US), and as such the risk is worth it.
I recall being at the train station in Xi'an (a big tourist spot as it's where the teracotta warriors are) and seeing several undercover cops bust a 'gang' of pickpockets. Fairly violent but not even close to some of the violence I've seen. The violence, however was never directed at me and I've never felt scared living here.
There is a HUGE police/security presence in China because the government is so worried about any unrest. I went to the Chinese Super League soccer on the weekend and there were more military, police and security than there were spectators!! I'm not kidding! Therefore if you were to ever encounter any trouble it's probable that some sort of police or security would not be far away.
I too have plenty of photos from China but at present am using a pentax as I just got rid of my rebel.. does this mean I can't post?
