Pressure to review six Miami police-involved shooting deaths of black men dating back to the last summer intensified this week when the American Civil Liberties Union and the NAACP asked a civilian panel wielding subpoena power to weigh in on the controversy.

Local NAACP President Victor Curry, following the police-involved shooting death of Travis McNeil last Friday, called on the Florida Attorney General to intervene and asked U.S. Rep. Frederica Wilson. D-Miami, to pen a letter to the Justice Department. Curry has also contacted the Rev. Al Sharpton, the well-known civil rights activist, to urge him to visit Miami and lead a community rally. No date has been set for the visit and rally.

Meanwhile, the ACLU presented a letter Tuesday to the city’s Civilian Investigative Panel, listing dates and names of the men killed by police between July 2010 and February 2011, and one killed by a Miami-Dade officer. They said the number of shootings is disproportionate when compared to larger cities like New York. That city, whose population is 20 times larger than Miami, had just eight police-involved shootings in 2010.
