Whenever there’s a police shooting by a Chicago cop, it’s investigated by the city’s Independent Police Review Authority. Since its 2007 creation, IPRA has investigated nearly 400 civilian shootings by police and found one to be unjustified. Lorenzo Davis was a supervising investigator with IPRA. He joined the agency in 2008. According to IPRA internal records obtained by WBEZ, he was fired earlier this month after resisting orders to reverse his findings that several civilian shootings by police officers were unjustified. WBEZ’s Chip Mitchell revealed the story Monday and joins us now with more details and the reaction from some elected officials. (WBEZ/Chip Mitchell)
