My heart is still broken over the murder of Sen. Robert F. Kennedy 50 years ago today.

Accordingly, I continue to hold members of his family in my heart as they continue to grieve over his death while running for the presidency of the United States.

But … I want to end this discussion that Sirhan Sirhan did not act alone in the Los Angeles hotel kitchen that night. I want to end the myth that there was another shooter in the room.

As you might already know from the blog, I am not a conspiracy theorist. I have dismissed the notion that someone other than Lee Harvey Oswald murdered Bobby Kennedy’s brother, the president, in Dallas on the bright, sunny November day in 1963.

None other than Robert Kennedy Jr., the third-eldest of Bobby and Ethel’s 11 children, believes Sirhan did not kill his father. I do not intend here to disrespect RFK Jr.’s belief in a second gunman, or that someone else fired those shots.

I wasn’t there when Bobby was mortally wounded; however, neither was his son.

I do know that Sirhan yelled, “Kennedy, you son of a bi***!” before firing a revolver into the back of the senator’s head. Sirhan, an immigrant from Jordan, hated Kennedy’s strong pro-Israel stance as attorney general and then as a U.S. senator. I also know that members of Kennedy’s entourage grappled immediately with Sirhan after he fired the shots. They wrenched the pistol from his hand; the bullets were spent.

Sirhan was effectively caught in the act of changing the course of U.S. political history.

He fired the shots that killed Robert Kennedy. He was sentenced initially to death; but then the Supreme Court struck down capital punishment, meaning that Sirhan would serve a life sentence in a California prison.

He did the crime. He will die behind bars. I continue to mourn the victim of his heinous act of violence.

Please, let us stop promulgating the myth that Sirhan didn’t do it.
