Quote:The law requires the Division of Criminal Justice to investigate whenever a law enforcement officer, while performing his or her duties, uses deadly physical force that causes someone's death. It must also determine whether the officer's use of deadly physical force was appropriate under standards established by statute and submit a report of its findings and conclusions to the chief state's attorney. The division is a state executive branch agency headed by the chief state's attorney, and is in charge of the investigation and prosecution of all criminal matters in the Superior Court.

absolutely an investigation must prove the officer was justified using lethal force. 

 

Nothing must be proved.  The investigation must prove the officer acted beyond what a reasonable officer would do in the same situation.  AKA, the burden of proof in on the prosecution (and in this case, it's not even the prosecution), not the defense.  Never, ever, ever has the burden of proof ever been on a defense.  If it has been, its been ruled unconstitutional.
