California Governor Jerry Brown has vetoed a bill that would have allowed judges to inform juries when a prosecutor has intentionally withheld evidence, according to the San Francisco Bay Guardian. Assemblymember Tom Ammiano, sponsor of the bill, said in a statement "we need this bill to stop the few prosecutors whose zeal for convictions lead them to cut corners on justice. We can’t wait decades to free the innocent while the true perpetrators run free.” Brown said he was vetoing the bill because it would intrude upon the judiciary's role in instructing juries.
