If the mob killed him they've have told us by now. There's no political need to cover for the Mafia.

Whoever ordered it is someone that outing would cause political upheaval over.

So with your own government or a foreign government that is supposedly our ally.

But even our own government when it fucks up gets thrown under the bus by opposing party.

That's why my money is on Israel, because that's the one group that neither Dems or Repubs ever, EVER shit on. Even when they deserve it.

The mob killed him because he made RFK the AG. Sam Giancana almost certainly played a role in getting JFK elected in the first place by rigging the vote in Chicago. A number of former associates have claimed that he openly declared that he had "his guy" in the White House, and in return he expected JFK to call off his brother. Instead, he put him in charge of the Justice Department and gave him free reign to go after the mob. Giancana was furious.

There's also quite a lot of evidence that certain intelligence agencies had previously worked with Giancana and other mobsters on ways to remove Castro in Cuba. The mob wanted that just as much as the government did, so they could have their casinos back.
