President Trump says crime is a serious problem and that he’s going to do something about it. His first move was to nominate Alabama Senator Jeff Sessions to be the new attorney general. Sessions, a former federal prosecutor, is widely known for his “lock ‘em up” philosophy and tough stances on drugs and immigration. As the first 100 days of the Trump presidency recede into history, it is a good time to pause and assess what’s in store for the American criminal justice system.
