It is always shocking to hear a stealing story. I think that KARMA is always at work -- that whatever you do, will be returned to you, a hundred times over. No one gets off "free" in life. You pay for it, in this lifetime...or the next!
Good looking, well dressed people steal. Multilingual people steal. Even rich people steal, famous people steal and I doubt it has anything to do with nationality.
it's possible that they only did if for the "rush" - or getting something out of nothing... people are weird - or maybe sick... (eg winona ryder)
