Who's to blame (in addition to the thief, of course)? The girl! It is amazing how many people young or old, male or female, white-black-yellow-red just have a phone (especially an expensive one, so everybody can see) in their hand in the weirdest places (e.g. a packed metro train in Rome), actually looking at video clips or whatever. Well, they make it easy to the pick-pockets, I don't feel sorry for them.
