Presumably the political changes caused by Hoovers death and the need to find a replacement and get him approved in Congress means JFK never drives through Dealey Plaza in November of '63 and Oswald never gets a chance to shoot JFK like he did. JFK might still be assassinated by Oswald or someone else but under different circumstances than OTL.
That presumes J. Edgar's death is proximate with JFK as PotUS. If you push the death back, to the late '50s, you make it moot.
If you push it back into the '30s... Could you see the new Director making the
Mafia a major target in the '30s? (J. Edgar denied it even existed, & there's some evidence he was being paid off by Frank Costello.

)
Or, could the new Director ask for even tougher Prohibition?

Parker, it will be a mixed bag. On the one hand he advocated going after the nation of islam, by trying to promote more Malcom X style's splits between Elijah Muhummad and the top brass. On the other he said, denying the Negro his equal place in america, is more dangerous than an H bomb.
Parker, as Chief, also reportedly used blackmail.

(Can't recall a source, tho.

) He did carry out a pretty strong effort against the
Mafia (tho as I understand it, the L.A. Mob wasn't exactly the Genoveses

).
