The civil rights leader spoke Monday night at an NAACP meeting for the Miami-Dade branch, where he announced that he'd already written a formal request to the Justice Department, with Congresswoman Fredricka Wilson, asking them to investigate whether police misconduct may be to blame in these cases.
"We need to examine, from a federal level, how you can go over 20 months, I think it's 22 months, with no shootings and then all of a sudden in seven months it's about a shooting a month," Sharpton said. "There's something that changed."
Since July 2010, seven African-American men have been shot and killed by Miami Police, two of them reportedly unarmed.
Activists Demand Investigation Into Miami Police-Involved Shootings
Miami Police Chief Miguel Exposito has been under fire by critics, including Mayor Tomas Regalado, who say his leadership has fostered a "shoot first, ask questions later" mentality in the department.
Over the weekend, Exposito sent a letter to the Miami Herald, saying he has no problem with a federal investigation.
"I welcome a federal probe into the Miami police-involved shootings. So much so that I invited the FBI to be present at the post-shooting reviews conducted under my watch," Exposito's letter reads. "As mentioned, I embrace a federal probe into our shootings; however, I also welcome a probe into the political interference that is compromising the integrity of the Miami Police Department."
