Grand Jury Reform Act of 2017 This bill conditions a state or local government's receipt of funds under the Edward Byrne Memorial Justice Assistance Grant program on the state's compliance with certain requirements following an incident involving the use of deadly force by a local law enforcement officer that results in a person's death. Specifically, the governor must appoint a special prosecutor to present evidence before a judge to determine whether probable cause exists to criminally charge the law enforcement officer. The hearing must be open to the public.
