John Lewis, the late Congressman and civil rights hero, authored a law in 2007 that tasked the Justice Department with reopening and reinvestigating racially-motivated killings from the Civil Rights era. More than 15 years later, the Justice Department has failed to bring charges in nearly all of the cold cases it has reopened.

On our weekly podcast, On The Merits, Bloomberg Law reporter Ronnie Greene talks about why the DOJ has had such little success prosecuting these cases. Moreover, he says, civil rights advocates worry the Justice Department's lack of results may cause Congress to lose patience with the program and defund it.
