Going against the grain in here, I think my mom would have decked him too. Both the "adult" on the skateboard and the little kid weren't aware of their surroundings, I would expect that of one more than the other. If you can can bring a cameraman you can make sure your target area is clear.
Wrong. I used to skateboard, and if you are in a park you check out your line before you start and make sure its clear. Once you start skating, all focus is on the board, or the obstacle you are trying to do a trick on/up/over/etc... In this case he was going for a flip trick with a turn, there's no way he was able to see that kid in front of him. Camera men are focused on the screen of the camera making sure they get the shot, also not able to see the little kid that is NOT supposed to be in the way. Not skaters fault, not kids fault (kids will be kids). This is all the ghetto bitch moms fault, and i hope she got hers!
