Screenshot/CNNCarl Dabadie Jr., who served as police chief when an officer shot and killed Alton Sterling in Baton Rouge, Louisiana, in 2016, announced his resignation and eventual retirement on Monday. In a letter dated July 24, Dabadie hinted that his departure was in part because of a strained relationship with Mayor Sharon Weston Broome, who campaigned in 2016 on promises to replace the chief. Broome and others had been critical of the Baton Rouge Police Department in the wake of Sterling shooting and amid allegations that top brass had tolerated excessive force and racist rhetoric from officers. “I have had the honor and privilege of leading one of the finest police departments in the country and I will forever be thankful for that opportunity,” Dabadie wrote in the letter to Broome that was published by the Advocate.
