You were doing fine until your last sentence.
Why so? Police Chief Dominick Arena never asked Kennedy why he had not reported the accident for nine hours. The DA never pressed for an autopsy, and then did so halfheartedly, and was shot down. Judge Boyd blatantly interfered in examination of the witnesses and supression of information. The state court granted Kennedy's request to keep the inquest "private," and prohibit the publication of the inquest testimony until after the Grand Jury met, thus depriving the Grand Jury of that information.
And -- my favorite -- Judge Paquet brought a priest to sit beside him at the Grand Jury proceeding. "The Reverend Donald Cousa, pastor of St. Elizabeth Roman Catholic Church, stood up in full regalia and requested that 'prejudice was to be set aside and replaced by charity.'" After the cursory testimony of four minor witnesses, after a whole 40 minutes, the DA decided it was over. End of story. Move along -- nothing to see here. He's a Kennedy, ya' know.
