Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

When James Bookhout pretended to be Jack Ruby in the garage and posed for this staged picture shooting Oswald, he used his middle finger as his trigger finger, extending his index finger right over the gas escape space of the barrel, which no one would do if he was really firing the gun unless he wanted to blow his finger off. So, why did he do it? It's because it was known that Ruby's index finger was partially amputated. Except: it was his LEFT index finger that was partially amputated, not his right. Therefore, it made no sense for either Ruby or Bookhout to fire with his middle finger. But obviously, misinformation went down the pike, and it resulted in this ridiculous picture.
