Well let's put it this way - they both didn't fail their lie detector tests, did they?
And they weren't inconclusive either.
Perhaps, but what does it change about the case, if lie detectors are simply inaccurate ? It alas does not prove anything.
There may indeed have been uncanny things happening at Amityville (as in other places). However, although I won't follow Escargot's footsteps calling the whole story "bollocks" (as I am no expert), I am afraid that any discussion of the case is fundamentally flawed / biased by the fact that it almost immediately gave way to a book, The Amityville Horror : A true Story
, which was, it appears, full of non-confirmed information (to speak politely). You may have a look at the "Criticism and controversy" section of the wikipedia page here (https://en.wikipedia.org/wiki/The_Amityville_Horror
) for a selection of fake data that got into the story (for instance, mentions of footsteps in the snow when there had been no recorded snowfall).
So, most unfortunately, through the book, and through the interests of some participants (if I had been de Feo, I would also have attempted to plead insanity through "hearing voices"), fiction interminggled with what may or may not have happened ... Hence it is probably not the best case to investigate weird phenomena.
I suspect that's what spurred Escargot's vigorous answer. She probably did not intend to insult anyone
