This would have gotten very interesting if he had tried his experiment on the sidewalk outside of a schoolyard or daycare playground. Unfortunately his experiment has a confusing methodology because he is introducing himself as a variable in the testing. And barging into closed rooms completely complicates the point. Then again, maybe his objective is simply to stir up some discussion. I'd like to see this tried with some less irritating filming method. Perhaps a small camera mounted to a moveable remote control device with a sign on it indicating that it is conducting random anonymous surveillance.
