In 1965, Mary Jo Kopechne drowned in Ted's Kennedy's car. In 2023 Obama's personal chef drowned in 8 ft of water off Martha's Vineyard while paddle boarding with an unidentified partner.
Moral don't get in the water with ???
Well, it is a fact that Ted Kennedy left Kopechne to drown in an Oldsmobile that he drove off the Tallahatchie Bridge, oops, rather the Chappaquiddick Bridge. (Ode to Ted Kennedy, Bobbie Joe Gentry, oops, Ode to Billie Joe).
Tafari Campbell's drowning investigation has already gone the was of the White House Cocaine investigation, i.e. nothing to see here, just keep moving.
Thus to answer your question, no the truth will not be told in the latter instance.
