I think I see your point. Consider the R's as innocent for a moment: once the RN was discovered and read, BR wouldve been instantly ruled out as 'playing a prank'. They knew at that moment there was a serious crime. That their daughter had been removed from the house. They knew their 10 year old son was incapable of the RN.
Didn't you?
That makes it more than just a 'family' emergency, as if they were missing a pet or something. Innocent parents would've known it to be a serious crime.
Placing myself in that position, however, calling 911 would've happened first and without hesitation. The reason for this is because the perp could be retarded or insane, and that means every minute a child is with them puts them more at risk.
Many RDI wouldn't have called 911 right away, apparently preferring to gamble with a child's life instead by putting faith into the perps hands, and assuming the RN to be factual.
Thats pretty odd considering how outlandish the RN was!
RDI has multiple and varied claims of the R's 'not reacting the way I would'.
You don't have unlimited funds and connections at your disposal (or maybe you do), but I am going to go with "you don't". John did and John had connections and his daughter's life was threatened so he calls 911 - okay - but how do you justify their calling their friends too.
They were not worried about JB being beheaded. AT ALL.
