Sure, and Teddy, Bobby, and the whole Kennedy clan allowed LBJ to sit at JFK's desk and never a peep out of them for 40 years?

Actually Bobby was also murdered less than five years later just after a victory in the California primary that might have propelled him to the Presidency. From there he could have re-opened the investigation without interference from Lyndon. Having two brothers murdered in less than five years may have been enough to silence Teddy and the rest of the clan.
