Seim pulled the deputy over because he says, he suspects the officer of stopping people in an unmarked car-- a violation of Washington state code.

But Seim lets the officer off easy.

"I'm  not going to write you up today. hold you guys accountable," says Seim on the video.

The rest of the exchange stays civil.

Eventually the deputy drives away - after the activist tells him to, "Stay safe out there."
