“Attorney General Jeff Sessions seems to believe that the future of law enforcement is in the past. During a speech to law enforcement officials last month, he talked up the ‘new challenge of violent crime‘ and the need to put ‘bad men behind bars.’ Presumably he meant more bad men, since plenty are already incarcerated; just as he presumably meant the “new challenge of peacefulness,’ since violent crime is near record lows. But never mind pesky facts, Sessions is determined to be every bit as tough on crime and bad hombres as his more colorful boss.”
