The issue came to a head in January 2016, when a federal judge sanctioned one city lawyer for intentionally concealing evidence and another for failing to make a reasonable effort to locate key records in a lawsuit stemming from the fatal 2011 police shooting of Darius Pinex. In response, Emanuel asked former U.S. Attorney Dan Webb to lead a review of the department's handling of police misconduct cases. Webb found no pattern of intentional misconduct among city attorneys, but he also recommended more than 50 reforms to address problems in the office. Patton instituted those reforms, along with several other measures he made immediately after the Pinex ruling.
