MIAMI (CBS4) — A retired FBI chief says he doesn’t consider a string of fatal shootings by Miami police officers to be a drastic increase from previous years.

Paul Philip is the former head of the FBI’s Miami office. The city hired him in January to review Police Chief Miguel Exposito’s performance and department policies.

Philip’s report notes that Exposito is due to retire and recommends the city start looking for his replacement. He did not say whether the fatal shootings of seven black suspects over seven months were justified.

City Manager Tony Crapp says the report will help the police department move forward. Mayor Tomas Regalado says the report “sends a message to the troops that there will be changes.”

Exposito said concerns cited in the report will be discussed with Crapp.
