good in a case where following the law would do grave injustice, bad because of local prejuidice would let perpetrators walk. Example would be the OJay case and many whites indicted for murdering blacks but could not be convicted in certain courts. The worse thing that could happen is get someone like me on a Grand Jury where the Jurors (if they only new) could run hogwild on any subject they wanted. We would indict a ham sandwhich that both lincoln and booth took a bite out of. :)
