MIAMI (AP) - Miami's former police chief wore an FBI wire to record conversations with city officials to investigate whether a proposed contract buyout might be a crime.
    
Ultimately the FBI and Miami-Dade County prosecutors determined that no violation occurred in discussions about giving former Chief Miguel Exposito a $400,000 severance package. The discussions involved Mayor Thomas Regalado, the former city manager and others in 2011.
    
A closeout memo from prosecutors said Exposito believed the buyout could be an attempt to bribe him into stepping down. Exposito and Regalado had clashed publicly over the legality of video gaming machines and Exposito also was criticized for police shootings of seven black men and boys.
    
The buyout never happened and Exposito was fired by the city commission in September 2011. He is appealing that termination.
