To all: whatever you think, do your research before posting here.
I would suggest that the problem is that you haven't done enough research on your own.
But it's the assassination of RFK which I find to be much more of a cover-up. Audio evidence uncovered in the last year has shown that 10-13 shots were fired at RFK, while Sirhan's gun held only 8 shots.
And further analysis by other experts say that there are only 8 shots and the analysis you speak of is wrong. I'll also add that "during a reexamination of the case in 1975, the Supreme Court ordered expert examination of the possibility of a second gun having been used, and the conclusion of the experts was that there was little or no evidence to support the existence of a second gun." (per wiki0
Gunpowder in RFK's hair shows the shooter was very close and shot from the rear, but Sirhan was in front of Kennedy and shot from 2-5 feet away.
Actually, Kennedy's head wound was from the side, behind the right ear, not in the back of the head. He was shot from the side.
Again, per wiki, "Several witnesses, though, said that as Sirhan approached, Kennedy was turned to his left shaking hands, facing north and exposing his right side to Sirhan."\
How did Thane Eugene Cesar get hired to be in the guard contingent that day (his first)?
Again, per wiki:
"Thane Eugene Cesar has often been identified by proponents of alternative theories as the most likely candidate for a second gunman in the assassination. Cesar had been employed by Ace Guard Service to protect Robert Kennedy at the Ambassador Hotel. During the day, however, he worked as a maintenance plumber at the Lockheed Aircraft plant in Burbank, a job that required a security clearance from the Department of the Defense.
When interviewed, Cesar admitted that he pulled a .38-caliber revolver at the scene of the shooting. He eventually acknowledged that he owned a .22-caliber revolver such as Sirhan used and showed it to LAPD sergeant P. E. O'Steen on June 24, 1968. Cesar submitted years later to a polygraph examination performed by Edward Gelb, former president and executive director of the American Polygraph Association, which asserted that Cesar denied any involvement in Kennedy's assassination and the polygraph test indicated that he was telling the truth."
I'll also add that Cesar was called in to work security at the last minute. Were the conspirators just lucky that their triggerman was called in? Kind of crazy to base your plot on luck.
What happened to his .22, which vanished before ballistics could be done on it?
Why is that relevant unless you can tell me that ballistics said Sirhan's gun didn't kill Kennedy?
What about the girl in the polka-dotted dress who allegedly said "we killed him"?
What co-conspirator trying to get away shouts "We killed him"? Do they want the police to arrest them? The obvious explanation is NONE - the person was misunderstood.
There's an enormous amount of data, both forensic and eyewitness, that suggests an inside job.
Are there still some unanswered questions perhaps? Sure, but to post all this as if there is no answer to any of it is a bit much when a 5 minute search on wiki turned up most of this.
