i'm so sorry hun, how horrible! I remember while i was shopping over Christmas Time, i had my purse in the cart and, although i was watching it the whole time, a kind gentleman stopped and chatted with me that i should physically hold on to my purse at all times while shopping. He told me a story that was pretty much a replica of yours, how a couple of people distracted his wife for just 10 seconds and she turned around and her purse was gone. Now i never let it go when i am out.
I'd imagine some people are more crafty though and can probably take your wallet out of your pocket if they wanted! It's so hard to trust people when you are out and about.
