The main argument has been won—that there was a conspiracy to murder JFK—and the only real argument concerns some of the details. From Kit Knightly at off-guardian.org:

Today marks 60 years since the assassination of John Fitzgerald Kennedy, 35th President of the United States, and the last of any worth or note.
There is the expected flow of official story reinforcement, a dabble of sentiment, a little bit of “new evidence” which handily backs up the Warren findings.
Alt-media channels were even subject to it, with one “red pill” going around claiming “Oswald’s handler” was an Israeli and Jack Ruby was Jewish, which means Israel killed Kennedy. Factless nonsense, seeking to both reinforce the lie that Oswald was the shooter and tar JFK truthers with the antisemitism brush.
Mainstream articles try to tie Oswald to Cuba or the USSR, securing the decades-old fallback that “the commies did it!” and casting any US cover-up as an attempt to avoid a nuclear war.
That or they just flatly assert lies older than the brainless husks repeating them, like this one in TIME, where their “history reporter” doesn’t even mention the Church committee finding of “probable conspiracy”.
