One past Supreme Court case that the Justice Department must contend with, as it tries to sway the justices to sign off on the use of the obstruction charge for January 6 rioters, is a precedent sometimes referred to as 'the fish case'.
In the 2015 case, a commercial fisherman was catching undersized red grouper off the coast of Florida, then had them tossed back into the Gulf of Mexico, attempting to prevent federal authorities from catching his illicit fishing practices.
