It appears that two of the agents couldn't fulfill their regular duties of riding on the back bumper of the presidential limo as they had in past motorcades. A driver/agent
was assigned to take their place. He was given command of the AR-15, a weapon he never qualified on. As the motorcade traveled through Dealey Plaza, a passing train
set off three railroad torpedoes near the grassy knoll at the worst possible moment. The railroad torpedoes are used as a warning device to warn a train to slow down.
They're spaced 20' feet apart and sound just like a bolt-action rifle being fired three times. They emit a puff of white smoke after they explode.

The driver/agent thought the motorcade was under fire and prepared to return fire. He grabbed the AR-15, safety off, finger on the trigger, when JFK's limo driver braked
for an instant. This caused the followup car to brake, causing the agent to fall back and reflexively grip the weapon and fire three rounds with one trigger pull. The crowd
ran towards the grassy knoll looking for the shooters, but found no evidence of a gun being fired.

When the motorcade arrived at the hospital, the Secret Service called Bobby Kennedy and told him there was an accident. Bobby is the only one who had the authority to order
a coverup. He thought it would be more befitting if it appeared his brother died from an assassin then from an accident.

The FBI has uncovered thousands of records connected to the assassination of former President John F. Kennedy as a result of President Donald Trump's executive order to release the files.

Axios first reported that the FBI released 2,400 records tied to the Nov. 22, 1963, assassination of Kennedy, which were not provided to the board that reviewed and disclosed the files.

When the Office of the Director of National Intelligence (ODNI) submitted its plan to release the JFK files, it reportedly disclosed the existence of the records.

Fox News has confirmed with a person familiar with the records that the files were uncovered during the review.

Besides everything else that's been said here about him, he was a hothead mental case that wanted to make a political name for himself one way or another. He had already tried to assassinate General Walker with the same rifle earlier.
