I 40 year old man pushes a kid just for skateboarding in a skate park! Whats the logic behind that? Then then man who helped build the skateboard tries to talk some sense, and gets his skateboard thrown then gets choked.

You could see the anger on the kids face, he was about to strike the man down. The other man who claims he helped create the skate park also helped calm down the other skaters who were about to beat down the security guard. The video is below:
