U.S. Marshals sometimes act like local police, but with more violence and less accountability. That’s according to a new investigation led by the Marshall Project. Reining it in is no easy task, according to co-author Simone Weichselbaum. And the Marshals, like other federal cops, regularly deputize local cops. That makes accountability for misconduct even more difficult, according to Patrick Jaicomo, an attorney at the Institute for Justice.
