The separation of politics and criminal law enforcement has long been viewed as a critical feature of our American system of governance. Beginning with the 2016 presidential campaign and its cries of “lock her up” directed at the opposing candidate, there have been questions about the extent to which the current administration would respect that separation or, instead, would move the country away from its fundamental commitment to the rule of law. Those concerns have grown in intensity because of actions by the President and Attorney General in characterizing the Mueller report before its release to the public; seeking the reduction of criminal penalties, supporting the withdrawal of guilty pleas, and exercising pardon and commutation powers to benefit friends and allies of the President; the launching of an investigation with the apparent intent to impact the upcoming election; and the labeling of certain communities as “anarchist cities” as a step toward cutting back on federal financial support. Building on his extraordinary career in federal law enforcement, Chuck Rosenberg, who has held a series of high-ranking positions in the U.S. Department of Justice, including the FBI and the Drug Enforcement Administration, and who is a widely respected legal analyst, offers his perspectives on this important issue.
