These stories remind me of the pimped out cars some people apparently drive in the US.
Do you honestly think no one's going to steal that jewelry off the back of your car when you leave it on the street for an hour?
Having nice things is great. I love having nice things. But when it shows that I'm walking around with 500 euros worth of stuff on my person, I'd get paranoid every time I come close to a crowded place. Think about it, how much does some of the tech you take with you on the street cost?
Not saying I'm dragging a fortune with me every day, but I know people who do, and I'm absolutely certain there are people who have a lot more expensive stuff on them.
Sorry, I went off on a personal tangent there. Anyway, message seems pretty clear: If you can't be assured of the safety of your valuables -like every time you're out of the house with them-, be very careful, or just don't do it. I know real life mugging isn't prevalent everywhere, but hardly anyone would have a problem with it on the internet, or so it would seem.
That said, reading stories like this puts a smile on my face. They remind me why I don't play MMORPGs.
