Query: hoax, hoax, and hoax

Really, this book shouldn't really be taken seriously. You can read most of this guys 'predictions' on the johntitor.com website. Most of his predictions are general/broad, and follow several media things like movies and other futuristic things etc like the Terminator. Some of the predicitons and things he said are said to be from an RPG game that was cancelled in the 90's. Apparently, his 'time machine' pictures are posted on that website, but even those are said to be old pictures of a radiation detection vehicle. It's all very sketchy, and many many holes have been found in it, so don't always believe everything you read.
