The shake-up in the Sansom Park Police Department seems to have taken everyone by surprise. That’s about 25 percent of the entire police force for the city of 4,500 people. Mayor Jim Barnett isn’t saying much but he does confirm there were allegations of sexual harassment and violations of department policy. Acknowledging this is embarrassing to the city, Barnett says they may have to rely on their volunteer reserve force for the time being. The city council meets on Thursday to talk this over.
