Federal prosecutors declined to bring charges against law enforcement officers in the United States facing allegations of civil rights violations in 96 percent of such cases between 1995 and 2015, according to an investigation by the Pittsburgh Tribune-Review newspaper. The newspaper examined nearly 3 million U.S. Justice Department records related to how the department's 94 U.S. attorney's offices across the country ... handled civil rights cases against officers. The data included cases referred to the Justice Department by the Federal Bureau of Investigation and other agencies. Overall, prosecutors turned down 12,703 potential civil rights violations out of 13,233 total complaints. By contrast, prosecutors rejected only about 23 percent of referrals in all other types of criminal cases. The findings could bolster arguments by activists, such as those involved in the Black Lives Matter movement, who claim police officers are rarely held criminally responsible for their misconduct. The report comes just days after the U.S. attorney in Manhattan, Preet Bharara, announced he would not press charges against a white officer who killed an unarmed black teenager inside his own apartment in 2012. The most common reasons that prosecutors cited for declining to bring civil rights cases against officers were weak or insufficient evidence, lack of criminal intent and orders from the Justice Department.
