The high stakes poker game had several participants. Oswald was the CIA's poker chip contribution, as he may have been a willing player due to anti-Cuba activity; Hoover covered for the mob, as Mossello supposedly had pictures of Hoover and his gay lover and threatened to blackmail him; Murchison (and maybe Hunt) was the big oil poker chip, who supplied the cash to preserve the Oil Depletion Allowance. Conveniently, Oswald got the Tx Bk Depository job a month before the assass. And LBJ gave his blessing and only God knows what else.

The big players got what they wanted in the end. We may never know for sure, but it still stinks and took some big balls to pull it off.
