Please tell us what they, or any police force can do to prevent and or investigate, to solve the all important, deadly pickpocket folks. Aside from plain clothes officers in high risk areas (which the may even have), though with limited resources and shy of 40M tourist a year ... good luck with that.
Didn't see who and don't know when ... yea, we get right on it.
They gave him good advice. Go back to shop, if even that is where it happened, and ask to see CCTV, if they even have. PoPo has better things to do. Aside from getting enough false insurance complaints from tourist, they can't be bothered.
50 years of playing tourist, never last anything, never had anything stolen, never been pickpocketed. Just use a little of that uncommon common sense. I does go a long way.
