Polls conducted in the last ten years indicate that 70% to 75% of Americans do not believe Lee Harvey Oswald, seen above in a photo taken while he was in the U.S. Marine Corps, acted alone when U.S. president John F. Kennedy was killed in Dallas in 1963. A March 2010 Gallup poll tells us the number might be as high as 81%. These are astounding percentages when you consider that reaching a higher level of agreement in a poll is nearly impossible. For perspective, consider that according to a 2005 article by New York Times journalist Cornelia Dean, only about 80% of Americans believe the Earth revolves around the sun.

Such overwhelming belief in a Kennedy conspiracy is easy to understand when reading the many contradictory accounts of the event. But filter out all the white noise and what attracts attention are the statements of two people who were highly respected—if not revered—in their fields. First, Secret Service agent Clint Hill, who was laying atop Kennedy to shield him as the limousine drove away from the scene of the shooting, testified that the President had a five inch diameter wound behind his right ear, indicating the exit of a bullet that had struck from the front. Other witnessess observed this too, but Hill was closest—literally inches away.

Second, Marine gunnery sergeant Carlos Hathcock testified that, utilizing the same rifle as Oswald, and shooting from the same range and angle and with the same weather conditions, he was unable to duplicate Oswald’s feat, even after multiple tries. Why is that significant? Because Hathcock was one of the best riflemen in the world, the winner of multiple shooting championships and a guy who in Vietnam documentably notched a kill from a distance of 1.42 miles. Oswald was a “marksman”—the lowest Marine designation for rifle qualification.

So what happened that day in Dallas when America lost a president? Was it Oswald who fired the fatal shot or someone else? We don’t know. We are not particularly what you could call "conspiracy theorists" around here. But we are realists, and realistically speaking, conspiracies exist in droves. That's why in federal court there are such charges as "conspiracy to commit wire fraud," and "conspiracy to commit murder." Oswald was well before our time, which makes him a historical curiosity for us, rather than a visceral part of our personal history. But looking at the case from afar, we certainly understand belief in a conspiracy associated with Kennedy's murder.

Photo of Lee Harvey Oswald on the cover of Life, published today 1964. Some people think this photo is fake. But Dartmouth College professor of computer science Hany Farid weighs in on this convincingly and his conclusion is the photo is legit. Great. Now maybe people can focus entirely on the laughable lone gunman theory. Just saying.
