WTTW, in partnership with the Department of Cultural Affairs and Special Events, present a FREE screening and discussion of the Indie Lens Pop-up documentary film, Peace Officer.  The increasingly tense relationship between law enforcement and the public is seen through the eyes of someone who's been on both sides: a former sheriff who established Utah's first SWAT team, only to see the same unit kill his son-in-law in a controversial standoff 30 years later. Now a private investigator, Dub seeks the truth in this case and other officer-involved shootings.
