Well, I just watched the "Athol House" investigation on DVD. 

What I thought was rather interesting was how J&G presented as evidence an image captured on the FLIR of a head, neck and torso of something.

The problem that I have is that the head and neck area of the image has the same body heat signature as that of a human, and the torso is cooler (in fact, it cools off at a point as if the image were to be wearing a crew neck tee shirt).  Furthermore, the left arm of the image seems to be bent up at the elbow and holding something.

Jason's profile pretty much matches the image that J&G found: Nicely exposed head area and wearing a short sleeve tee shirt.  In addition, J&G, while holding the FLIR and the "clam-shell," respectively, while they were doing the sweep, matches nicely to that of the image holding something.

Either these guys, knowingly, are presenting false-positives, or they are really amateurs; trying to find anything to show that "ghosts" exist.
