Nailed it. That is perfectly plausible due to the fragmentation information. Why has this not been brought out before? Crooked government covering for Secret Service agent who would have been exonerated anyway because it was an accident. THIS I do believe.
It is very plausible isn't it? I'm glad someone read the article.....
It has. See pages 925-929 of Bugliosi's book.
Bugliosi complements Donahue for his depth of research and knowledge, but there are holes in the story that he covers quite well.
Perhaps the explanation lies in a disturbing little detail that may or may not be true. The author says the SS agent who may have been the culprit was only on the presidential detail for a few months before the assassination, and wouldn’t have been assigned the responsibility for the AR-15 under normal circumstances ... but was given this responsibility because the veteran SS agents on the detail were hung over after a night of heavy drinking.
