Just watched the "Live Post Mortem" and was happy to see the guys call a spade a spade when it came to the Robert Bess footage. Not only did they state that they didn't believe his story, but also edited out the other questionable actions such as "the punch".
I'm impressed with the crew's integrity. Their willingness to basically say there was no paranormal activity in the thrown emf detector--to basically call the man a fake and a liar--was highly commendable. It would have been easy enough to state they weren't sure either way or to stand by a "fellow" investigator. I'm glad they weren't afraid to take a stand against fakery and risk the backlash from an older investigator who probably has a lot of supporters in the field.
I think it just adds to the credibility of Zak, Aaron, and Nick. Good job, guys.
