Whitney Bryen / Oklahoma Watch When Oklahoma prosecutors back a criminal justice bill, chances are it will become law. Oklahoma district attorneys lobbied for or against 47 bills from 2015 to 2018, according to a study published June 3 by the University of North Carolina School of Lawâs Prosecutor and Politics Project. The stateâs 27 prosecutors were most likely to support bills that proposed expanding criminal law or increasing punishments for certain offenses, but did lobby for nine more lenient bills, researchers noted.
