A town hall featuring South Bend, Ind., Mayor Pete Buttigieg devolved into chaos Sunday as the city struggled to respond to a deadly police-involved shooting last week. In his opening remarks, the 37-year-old Buttigieg, a Democrat and candidate for president, said he would send a letter to the Justice Department requesting that its civil rights division look into the June 16 shooting of 54-year-old Eric Logan, who was black. The mayor added that he would notify the local prosecutor that he'd like an independent investigator appointed.
