Your first rant... I don't think it was trivial at all. What that woman was doing was theft, or vandalism at the very least. She really should have had more common sense and decency in what she teaches her daughter. Those were there for everyone to enjoy. Good for you for reacting! I think your camera trick was priceless
Would have I done anything? No. I'm one of those people that sit by. Confrontation makes me physically ill, just like public speaking. When someone is in danger though I couldn't sit by. Again kudos to you for calling 911!
