In Europe, many of the pickpockets are Rom, or "Gypsies". Many others come from the former Yugoslavia. At the risk of sounding "un-pc" or some such, it's not intended as a racial profiling thing or a slur, but I lived & travelled a good while in Europe & I've seen it. I have also known Rom as well as Bosnians, Serbs, etc. & they are very warm & wonderful folks. It is said that they (the Rom) have "holy" permission to steal, due to some thing w/ the cross that I now forget. The "fake wallet" trick is a good one- especially when combined w/ a good curse (not curse words, but an honest-to-goodness, evil-eye curse) in a horse-skin wallet. The Rom revere horses & eating them is forbidden. Some cafes in Germany in towns with a high Rom population have gone as far as to put "We serve horse meat" signs in the windows to ward off "unwelcome" customers. Ugly, indeed, but it happens. Watch sudden outbursts around you & look out when someone is overly friendly for no reason & crowds your "space bubble" (American "space bubbles" are wider than those for most Europeans, btw)
