Former Attorney General Eric Holder slammed the current leader of the Justice Department’s decision to roll back policies he had implemented as part of a broader effort to reform the criminal justice system. Calling Attorney General Jeff Sessions’ new sentencing and charging memo “unwise” and “ill-informed,” Mr. Holder said the change in policy “is not tough on crime. It is dumb on crime.” In a statement on the new policy, announced Friday, Mr. Holder said the decision “ignores a rare bipartisan political consensus that has formed around sentencing reform effort and will take this nation back to a discredited past.”
