I just re-read the book, and i found several of his arguments quite good. For instance, would an intruder know where to find the sharpie pen with which he/she wrote the note, and why would he/she put the pen back? what about the pineapple which was never explained? he also said they couldn't move through the house without creeking. Also, Thomas claimed he COULD hear a scream from the basement upstairs. I also found it interesting that Thomas claimed with the light off, he could not see into the room where JB was found, although john claimed he saw her instantly. Finally, Thomas said navigating the house in darkness was impossible. Think what you will, but i think Thomas' book contains the answers and he provides logical proof to reinforce his argument.
