Justice Department launches review of San Francisco police

Posted: 01 Feb 2016 02:55 PM PST

The U.S. Justice Department said on Monday it would launch a review of the San Francisco Police following requests from city officials and community members. Although the American Civil Liberties Union had asked for a federal investigation into the San Francisco Police Department following the death of Mario Woods, 26, at the hands of police, the review will only result in recommendations, not court-enforceable reforms. "We will examine the San Francisco Police Department's current operational policies, training practices and accountability systems, and help identify key areas for improvement going forward," Attorney General Loretta Lynch said in a statement.

The vacant lots and crumbling houses that line a vast majority of the city's streets are evidence of Flint's descent from the home of General Motors — a bustling company town with a population of close to 200,000 — into the country's murder capital, with a population down by roughly half from its peak in 1960, and a poverty rate of more than 41 percent.

U.S. documents detail 2015 Amtrak train crash but offer no cause

Federal investigators on Monday released thousands of pages about the fatal derailment of an Amtrak passenger train last year in Philadelphia, but the central mystery of what caused the crash remained unexplained. The documents, posted online by the National Transportation Safety Board, include two interviews with the train's engineer, Brandon Bostian, who said he had no recollection of the moments before the accident that killed eight people. "Unfortunately, the last memory I have on the way back is approaching and passing the platforms in North Philadelphia," Bostian, who suffered a concussion, told investigators three days after the crash.
