It's the latest shooting that IPRA has determined to be in violation of use-of-force policies since Mayor Rahm Emanuel was forced by a judge in 2015 to release video of an officer shooting teenager Laquan McDonald 16 times. Between its inception in 2007 and December 2015, the agency investigated hundreds of shootings and found only two to be unjustified. Since then, however, five more shootings, including Dakota's, were found to be unjustified use of force.
