There are certain places where skateboarders are allowed to have the right of way. A skate park is certainly one of them. So when this guy was filming a part for a skateboarding movie, he ran into a snag - or a little boy. 

As you can see in the video, the child runs right out in the middle of the skaters path. In the middle of a trick, he collides with the young boy. He stops, and people rush to see if the child is okay.

The mother comes over, very angry, and assaults the skater. Now obviously she should be angry, but she chooses to pick a fight with the guy because of her negligence. She should have been watching her son, and certainly should not have let him wander into an area like that.
