Threats of harm to federal judges that aren’t reviewed for days. Investigations into suspicious behavior at courthouses that are sloppily done. Lack of money to identify and prevent acts of violence in and outside work.

Three years after it was warned by the Justice Department’s inspector general to improve security, the U.S. Marshals Service is languishing in its efforts to protect the nation’s 2,200 federal judges, according to a new report. That is putting federal judges in danger even as threats against them have almost doubled in the past five years.
