MIAMI (AP) -- A congresswoman wants the Justice Department to investigate the Miami Police Department and its use of deadly force in the shooting deaths of seven black men since July. Six of the men were killed by police (pictured above). 

U.S. Rep. Frederica Wilson, D-Fla., wrote Attorney General Eric Holder on Thursday to ask for a federal investigation. Wilson says only the federal government has the resources and independence to give "close, objective scrutiny" to the deaths. All but two of the men were armed when they were shot by police. The State Attorney's office is investigating.

A spokeswoman says the Justice Department is reviewing Wilson's letter.
