Awhile back there were people having this type of discussion here once the family started to speak to the media about 3 months after the abduction. IMO it is in the JVM interview (early august) where we get a glimpse of the disconnect in the case between LE and the Bobo's. If you think back to the initial reports of HB being dragged away, and then shortly after the TBI corrected this into the effect of HB being forcibly lead away from her home with no drag marks around the property. Once CB started talking to the media, JVM asked him about the lead away comments from LE and CB said that he saw HB casually walk away with her abductor, no leading or dragging or arm holding. JVM then asks KB if she has any information that LE has shared with her and at several different points in the interview, KB makes a point to mention that the TBI has told her it is a law that they do have to share any info and they have not told her anything. KB then says they have not cleared anybody that she is aware of, but the Bobo family and DS were never considered suspects. Then of course we have DB saying that LE told them weeks later that the blood found did belong to HB, and the only thing DB says after the blood comment was the local community has told them of some of the items found they believe could belong to HB. After that comment, the family spokesman assumes where DB was sitting and we do not hear from DB again. (I want to add that when DB is making his comment about the blood, it clearly sounds like somebody is trying very hard to make hushing sounds in the background. A hushing sound is unmistakable and came at a time that sensitive info was being shared.)Just my opinion, but I think the key words in your post are "with LE approval". I think from the moment Holly disappeared, the Bobos have been speaking out almost exclusively only "with LE approval". Since I have little to no faith in LE in this particular case, I think the Bobos have allowed themselves to be put at a great disadvantage in terms of clearing up the facts surrounding what Clint did or did not see and what can be done now to locate Holly.
To get back to your original post, it does seem as if there is a conscious effort to keep control over the actions and words of the Bobo's. IMO it would make sense that LE has advised them of sensitive info that should not be shared, but is it possible that this family is also getting some type of pressure from their local religious affiliations? After all, the family spokesman(a Baptist pastor who is not the Bobo's pastor) has went to the media several times to talk about the case, but when asked a question he does not give any answers except, I don't know. The county sheriff ( he gave a few interviews in the first days after the abduction) is also a Baptist pastor. The TN Baptist newsletter has released quite a few articles about HB. I think it is safe to assume the local Baptist community has a vested interest in this case, not just the local LE. Oh wait, or is it the other way around?
(I am not trying to be offensive to any Baptists, it is JMO when religion and politics (Governor reward) get infused into a criminal investigation, usually everything becomes a hot mess.)
