Via Daily Mail:
Jack Ruby made comments on the morning of President John F Kennedy’s assassination to an FBI informant that suggested he knew what was about to take place, according to new records released Friday.
Ruby, who was eventually charged with killing Lee Harvey Oswald, asked an FBI informant if he would like to ‘watch the fireworks’ with him as Kennedy’s motorcade drove through downtown Dallas just hours before the assassination took place.
The records are part of the JFK Files, which have been released incrementally over the past few months by the National Archives after being sealed for 25 years.
Oswald shot and killed JFK on November 22, 1963, in Dallas.
Just two days later Dallas nightclub owner Jack Ruby shot and killed Oswald as he was being transferred from city to county jail.
