Very similar to what happened to me a few weeks ago. I was running some errands on a Saturday morning when my wife called asking me to pick up a couple items at Walmart and I agreed to do it. I hate going to Walmart, especially on a Saturday morning. Of course I had to park a fair distance from the entrance and as I walked towards it, I heard a lady a couple rows away screaming as two guys tried to wrestle her purse away. Same question: should I ignore it or go try to help? I decided to go help and I'm glad I did cause it took all three of us to get that purse away from her!
