The other day while walking a little behind me along Medecin in Nice, my wife noticed a small hand reaching into my backpack. She jumped out and grabbed the boy's hand and made him open up his hand and release the stuff he had taken from my pack. There were three boys (around the ages of 10 to 13)working in a team to pick pocket tourists along the busy boulevard. They ran off and we did nothing beyond that. Today, I caught them at it again and stopped them from taking stuff from a lady's bag.
What should I do with them when I catch them at it? Should I bother to report it to the police?
