Denver’s safety department waited a year to discipline a sheriff’s deputy for grabbing a man who was appearing before a judge in a Denver County courtroom and slamming him into a wall.The deputy, Brady Lovingier, is the son of Bill Lovingier, who headed the sheriff’s department from 2006 to 2010. The safety department disciplinary report on the incident found “no legitimate reason” for Lovingier to attack inmate Anthony Waller in Judge Doris Burd’s courtroom.
