I watched a bit of this earlier and was intrigued enough to watch the other racism one with the kids spraypainting the car. Very interesting stuff, reminds me of my 200-level psychology classes where we learned about stereotypes and how they are normal and can exist without the "racism" often associated with them.
When the white kids wrecked that car in the park, only 1 call was made to 911 (while 2 calls were made about a few blacks innocently taking a nap in their own car because they "about to rob" someone), yet when the black kids were messing with the car in the same way, 10 calls were made to 911.
