The “Hero” wearing bullet-resistant vest underneath his shirt = prior knowledge of impending assassination
During that dreadful day in Dallas, one Secret Service man, Clint Hill would be required to perform as advertised and protect Mrs. Kennedy; the Jackie everyone loved and admired (Except @#$hole Emory Roberts) . She wasn’t sleeping around like JFK was, and was the devoted mother of two adorable children. Knowing that shots would be fired in his general direction, Agent Clint Hill has taken the precaution of wearing a ballistic vest unlike his peers who knew that their duties would not have to be performed that day. After running to the JFK limousine too late, he made sure Jackie didn’t kill herself falling out the limo trying to retrieve her husband’s brains and received a medal from the SS afterwards. He became the defacto “hero” America needed since the designated “hero” failed to corner patsy LHO in the TSBD and kill him.
