The release of tens of thousands of pages from the JFK assassination investigation will not clarify anything or end the conspiracy theories for those so heavily invested in such theories.  By its nature an investigation of this sort collects all pieces of evidence without regards to its credibility, so I expect we will see a lot of wacky claims regarding conspiracies and individuals and groups, like the Illuminati!, and a lot of people on social media republishing random and unsubstantiated documents as proof that their particular conspiracy theory is thus proved.  For those who can't find the document(s) they were confident existed, absence alone will provide definitive proof that the conspiracy existed.

Here is what I think happened:

On President Kennedy

Lee Harvey Oswald was the lone assassin and not part of a conspiracy.  The Warren Commission got its overall conclusion correct, but made major mistakes in its analysis, in part because the real scandal was the CIA and FBI covering up the evidence they had gathered enough information, in the three months prior to November 1963, that if acted upon properly, could likely have prevented the assassination. It was a bureaucracy protecting itself. And Lyndon Johnson was convinced Castro was behind the deed, and he did not want that to be the public conclusion because he thought it would lead to war with the Soviet Union.

For my prior analysis read A Cruel And Shocking Act. 

On Robert Kennedy

RFK was the target of Sirhan Sirhan, a Palestinian upset by Kennedy's support for Israel.  There is a small possibility that the fatal shot came from a guard or law enforcement officer in the chaos after Sirhan began shooting. 

On Martin Luther King

James Earl Ray was the lone assassin though it is possible that someone else encouraged his action.  Of the three events, this is the one I know the least about, and am least confident of my conclusions.
