"According to his own testimony, Kennedy swam across the 500-foot channel, back to Edgartown and returned to his hotel room, where he removed his clothes and collapsed on his bed. Hearing noises, he later put on dry clothes and asked someone what the time was: it was something like 2:30 a.m., the senator recalled. He testified that, as the night went on, "I almost tossed and turned and walked around that room ... I had not given up hope all night long that, by some miracle, Mary Jo would have escaped from the car." Back at his hotel, Kennedy complained at 2:55 am to the hotel owner that he had been awoken by a noisy party"
So he's complaining about the noise keeping him up while this woman's still at the bottom of the sea. The next morning (again from Wikipedia)...
"By 7:30 am the next morning he was talking "casually" to the winner of the previous day's sailing race, with no indication that anything was amiss.[2] At 8 a.m., Gargan and Markham joined Kennedy at his hotel where they had a "heated conversation." According to Kennedy's testimony, the two men asked why he hadn't reported the accident. Kennedy responded by telling them "about my own thoughts and feelings as I swam across that channel ... that somehow when they arrived in the morning that they were going to say that Mary Jo was still alive"
And the final kicker, he didn't contact the authorities until the body was found and the woman probably survived the crash. One last quote...
"Earlier that morning, two amateur fishermen had seen the overturned car in the water and notified the inhabitants of the nearest cottage to the pond, who called the authorities at around 8:20 am.[14] A diver was sent down and discovered Kopechne's body at around 8:45 am.[15] The diver, John Farrar, later testified at the inquest that Kopechne's body was pressed up in the car in the spot where an air bubble would have formed. He interpreted this to mean that Kopechne had survived for a while after the initial accident in the air bubble, and concluded that
"Had I received a call within five to ten minutes of the accident occurring, and was able, as I was the following morning, to be at the victim's side within twenty-five minutes of receiving the call, in such event there is a strong possibility that she would have been alive on removal from the submerged car."
So had he contacted the authorities she could have lived. And for all that he got a suspended sentence because he's rich and has a powerful family. I won't demonize the dead but I'm not going to sit by and let people lionize him either.
How is it that people can bash Michael Jackson after unproven accusations but let Kennedy off even though he admits to everything laid out above?
