SALT LAKE CITY (AP) — Two Salt Lake City men accused of setting fire to an empty police car during protests over the death of George Floyd have been charged in federal court. Arson charges filed Wednesday say they tossed combustible substances into the patrol car, feeding the flames that destroyed it. Each man could face at least five and up to 20 years in prison if convicted. Meanwhile, a Utah criminal justice professor resigned after writing an inflammatory series of tweets about the nationwide protests against police brutality. He says he realized his tweets were wrong and his resignation from Weber State University is effective immediately.
