A Marathon County judge has given a Wausau man 45 days behind bars for dragging a Wausau police officer with his car last April.  Sixty-two-year-old Bradley Latz had entered a no-contest plea to charges of recklessly endangering safety and had pleaded guilty to drunken driving causing injury.  Surveillance video shows the officer reaching into the car driven by Latz in an effort to remove the keys from the ignition.  Latz drove off as that officer hung onto the door for about 15 yards.
