A lot of people drop their guard when they travel to a different country, they are on vacation and relax the vigilance mode and are easy prey for the opportunist thief, some even make the tourist tell them where they have the wallet, it is simple put a official looking notice " beware of pic-pockets "
I saw this at the Eiffel tower in Paris, everyone coming on to the top most observation tower reading the notice and was reaching for the pocket where they carried the wallet and two guys watching the tourists, I walked over to the two and took out my wallet and asked them if that was what they were looking for, they dashed for the exit, no one paid attention to them tourists were looking at the view while these two were looking at the marks, I carry my wallet left front pocket, never rear pocket easiest place to lift it.
Or the women that place the hand bag on the shopping cart where the kids sit, and the best open so that anyone passing can lift the purse or the bag and vanish.
Try not to be an easy prey for the thief's, and when sitting at a restaurant women do not place or hang your bag on the back of the chair, you will not notice when the bag is lifted, "Police 101"
