So, apparently it was Oswald after all.
In preparation for the 45th anniversary of the assassination of John F. Kennedy, the Discovery Channel assembled a team of experts to re-investigate the shooting. According to its program that aired last night, modern technologies like blood-splatter analysis and computer modeling show that the shots came from the sixth floor of the Texas School Book Depository Building. The grassy knoll has been ruled out.
Don't expect this to convince too many people. Scientifically speaking, the case has been closed for decades. There are plenty of fishy things about Oswald and the CIA, but all the evidence points toward a lone gunman. Despite this, polls consistently show that most Americans believe in a "second shooter."
Conspiracy theories are seductive. When I was a sophomore in high school, I started a Web site to explain how the Apollo 11 moon landing was faked in a Hollywood studio by Stanley Kubrick. I found lots of photos where the shadows looked funny, a few where the crosshairs were missing or at strange angles, and even a video that made it look like the American flag was waving in the supposedly windless atmosphere.
