SALT LAKE CITY (AP) — A Utah criminal-justice professor has reversed himself again and resigned after posting inflammatory tweets about nationwide protests concerning race and police use of force.

Weber State University officials said Tuesday that professor Scott Senjo's resignation is permanent. He had previously stepped down in early June but changed his mind and withdrew that resignation shortly after.

The university had condemned Senjo’s tweets and believes his sentiments were “abhorrent."

Senjo’s Twitter account shows he tweeted support for damage done to CNN headquarters in Atlanta during protests in late May and tweeted at a reporter who said he had been hit by police in New York City: “Excellent. If I was the cop, you wouldn’t be able to tweet.”

In response to a tweet showing a New York City police car driving into people, Senjo commented: “That’s not how I would have driven the car into the crowd,” his Twitter account shows.

Senjo had taught at the university in Ogden for more than 20 years.
