Sirhan’s murder took place in front of many witnesses, some of whom (including NFL star Roosevelt Grier) immediately wrestled him to the ground, gun in hand.

Lee Oswald’s killing of John Kennedy is probably the most thoroughly-understood event in the history of the world. Oswald did it. There is zero question about that. If you harbor any doubt, read Conspiracy of One by Jim Moore or Case Closed by Gerald Posner. The case against Oswald is conclusive, and after all these years, there is zero evidence of involvement by anyone else, let alone the CIA. And to claim that someone other than Sirhan Sirhan murdered Bobby Kennedy is bonkers.

But that is where we are in American political life. It is fine to applaud Robert Kennedy, Jr.’s challenge to Slow Joe Biden, but let’s not forget that Kennedy is nuts.

[He’s an improvement over an aphasiac Biden, but … that’s not saying much. — Ed]
