MIAMI (AP) - The U.S. Justice Department has concluded that the Miami Police Department engaged in a pattern of excessive use of force in the fatal shootings of seven black suspects over an eight-month period.
    
The Justice Department's Civil Rights Division has been investigating Miami police since November of 2011. The shootings from July 2010 to February 2011 took place during the tenure of former Chief Miguel Exposito, who was fired in 2011 during outcry from black community leaders about the shootings.
    
The department also found deficiencies in tactics and supervision and delays in deadly force investigations.
    
Current chief Manuel Orosa made changes in police tactics in high-crime areas that sharply reduced confrontations and police shootings.
    
State prosecutors have so far not ruled any of the shootings as unjustified.
