Like who? You already said you have no experience in kidnapping. I cited an actual kidnapping case and a first-hand account of another reaction, which was similar to the Ramseys. You had no response to that, since again -- it didn't fit your hypothesis. Ignoring evidence doesn't make it go away.
The same rules apply -- in that you have no experience with the victims in this case, so you have no idea how they should or shouldn't react, let alone trying to psychoanalyze individual details of their reaction.
Yes, how they act is critical. If they had, say, jumped on a plane and fled to Mexico, that might be a good indication that they are hiding something. That they chose to call the police rather than searching the house -- that means nothing in relation to their guilt or innocence. That the father brought the body upstairs -- that means nothing as it relates to their guilt or innocence. You can talk about your "personal" experience (which you don't have with kidnapping) all you want. It doesn't cover up poor analysis.
Let's recap: You asked "what had changed" when John Ramsey searched the house, and that it was suspicious. I gave you the factual answer, which didn't fit with your hypothesis. You responded with, "That's a different subject." That's the very definition of changing the subject. If the answer to your question is "a different subject," then I'm not sure why you even asked it.
Do you have any proof that that was the MAIN reason they maintained their status as suspects, or are you just making that up? Cite, please.
They were considered suspects because:
a) Percentage-wise, the parents are most likely to be the perpetrators
b) The murder occurred in the house
c) The note was written in the house
Those are all perfectly valid reasons to consider them initial suspects. And they have nothing, whatsoever, to do with their conduct.
Not to mention that this is all a bit circular. If you start with the premise that how they acted is suspicious, then they are going to be suspects. And if you suspect that they killed their daughter, you are going to believe they acted suspiciously.
Your "suspicious acts" are based on poor analysis and a failure to grasp the facts. As I noted, a pretty significant part of your suspicion was easily answered by a very-well publicized fact that you didn't bother to know or look up. The rest of your "suspicions" are based on a faulty assumption: that there is one "right" way for victims to act when dealing with a crime. That is absurd on its face.
Not all mothers scream at the top of their lungs and go on a mad searching spree. Not all fathers find the body of their child and immediately think, "we'd better preserve this here crime scene!"
Who is "us"? You didn't work on this case. You noted above that your opinion is worth no more[/i] or less than anyone else's. You are as much an "armchair type" in regards to this thread as anyone. And all the background in the world won't make up for lousy analysis.
So here, I will quote John Douglas, who actually did a full analysis of the case, and is a 25-year FBI veteran and author. He compared the case to the Lindbergh's as well:
And this, by the way, jibes with my own REAL WORLD experience in seeing people in crisis situations.
