NO local prosecutor shall convene a Grand Jury or lead the prosecution when the case involves the use of deadly force by a local police officer. Prosecutors and policemen should have a close working relationship with each other, but too often prosecutors act more like defense lawyers than District Attorneys when a policeman is on the stand.
It is an unfortunate fact that some local prosecutors have proven themselves too biased to convene a grand jury or conduct a fair trial because they believe their own cops can do no wrong.
The Michael Brown case and the Eric Garner case are just the two most recent examples. A special prosecutor should always be appointed in cases like these.
