"Upon learning of the reporting issue, CPD immediately launched an in-depth review of every single aggravated assault and aggravated battery that occurred during 2012 and 2013, to correct the tracking of these crimes and bring the city into stricter adherence with reporting standards," the department said in a response printed in the IG report. "This in-depth review is ongoing, and where errors in victim-level reporting exist, they will be corrected."
