CHICAGO (AP) — A former Chicago police detective is suing to get his job back after being fired for posing in a photograph with another officer holding rifles over an unidentified black man lying on a floor and wearing deer antlers. The photo was discovered during an FBI investigation into police wrongdoing. The FBI uncovered the photo during its investigation of Finnigan, who was convicted in 2011 of leading a band of rogue police who stole hundreds of thousands of dollars from suspected drug dealers and ordered a hit on a fellow officer to keep him from revealing the scheme.
