VANCOUVER, Wash. – A man who drove his car through a group of protestors in Washington State was not arrested.

The incident happened Sunday at an event in Vancouver on Sunday.

Witness video shows Williams Wilson driving through the crowd.

Other video shows protesters throwing things at Wilson’s car.

Police briefly detained Wilson, but later released him.

Authorities say they did not have probable cause and that Wilson feared for his safety.

Wilson says, “I made sure there was nobody in front of me before I gunned it or whatever. I’d seen one lady in front of me. I made sure she was out of the way. Then I went through there.”

One witness says he is upset police let Wilson go.

Gregory McKelvey, a witnessing it all says “This guy [Wilson] was not worried about anybody’s life, driving through the crowd. It’s really a miracle that nobody was seriously hurt. I think it’s disappointing that police let him go.”

Now a petition is calling for Wilson to be charged with Attempted Vehicle Homicide.
