After influencing and writing a vast amount of legislation, all of it as evil and repugnant as himself, Edward Kennedy died forty years after disposing of an inconvenient mistress.
By accident or design, Kennedy’s car wound up upside down in the water, with Kennedy not in it, and his girlfriend in it. It retained an air bubble for a substantial period, which means that his girlfriend was alive for a substantial period. Kennedy then proceeded to construct an alibi, to conceal what had happened. His girlfriend may still have been alive at the time he was creating an alibi. Whether or not it was an accident that his car was in the water with his mistress inside and him not inside, it was no accident that she remained inside.
