An Arizona State University police officer resigned Monday rather than get fired for his treatment of a faculty member, the Arizona Republic reported.

Officer Stewart Ferrin stopped assistant professor Ersula Ore in May and ordered her to walk on the sidewalk, rather than the road, according to the Republic — and as she argued with him and refused to show identification, the incident escalated to the point that he was threatening to slam her into the police car, she kicked him in the shin, and he tackled her to the ground.

The incident, caught on video, went viral, sparking debates over police use of force, appropriate compliance, and race — the officer is white, and the professor is black.

A police report described her as extremely upset and strongly physically resisting arrest; she told an officer arriving at the scene she had just been slammed to the ground so, “Of course I’m going to fight back. Of course I’m going to yell.”

In his resignation letter to the university, Ferrin said the more than seven months of leave had caused “great financial stress and emotional anguish….”

“The lack of support, cooperation, and downright bias, coupled with an agenda to ruin my career, has become unbearable and I will not subject my family to this any longer,” he wrote.

Ore filed a $2 million lawsuit against Arizona State last month, the Republic reported. In the lawsuit she said she felt “degraded and humliated” by the “vicious attack,” and has since suffered “depression, anxiety, PTSD, irritability and panic attacks.”
