After personally interviewing James Tague, he made it aware to me that he was misquoted in Posner's book. Tague told me that it was not the first shot that caused his wound. Despite Tague's feeling that it was the second shot which hit him, it appears possible that he merely didn't feel any pain right away. It only created a few drops of blood. This supports the idea that he may not have felt the pain immediately.
Various theories suggest other shooters and other reasons for a missed shot.
Some of them involve a second shooter, as illustrated in the book Crossfire . This theory posits a second shooter firing a bullet and missing the limousine, hitting the curb. The bullet would have had to already had the copper jacket stripped from the bullet in order to explain the lack of copper found in the curb sample. The majority of theories such as this seem far more implausible and based in conjecture more than based in fact. This is simply an incorrect assumption.
