The officer was writing Wong a ticket.
Wong decided he didn't have to get a ticket, he would just leave.
The officer grabbed mister Wong as he began to sidle off.
Mister Wong then initiated a shoving match with the policeman.
In said shoving match Wong was pushed to the ground where his cheek got scraped.
The officer summonsed more officers and they restrained him, then took him to Saint Luke's hospital.
As far as I know, the officer did neglect to check mister Wong's birth certificate to find out how old he was before writing him a ticket or restraining him, so I guess you might have some sort of point. Wong looks only in his middle sixties to me but I guess they should have to confirm that.
Or something.
After the Rodney King incident I assisted in the training of Cadets in Erie County New York. We demonstrated how to use these tools so that at the end of the day everyone is safe and the bad guys are behind bars with a minimum risk of injury.
