Like Anyhoo, I have to agree with the completely sensible points that you've made, Anti-K. To deliberately point clues to themselves does sound inexplicably stupid, and so too the idea that one spouse would stand by and just accept the other one murdering their child. All I can say is that this whole case is one huge riddle, with bizarre things seemingly contradicting themselves. That's why I'm ending up speculating in riddles myself! There must be some explanation that would tie everything in together, somehow- whether it's following any logic or not!
Since this thread is about premeditation, I've swung around between considering it as a tragic accident that may have been deliberately covered up, possibly to hide signs of prior molestation? But, to me, this doesn't seem to fit. As I've said before, to me, that doesn't sit right with the parents' behaviour. Plus, since strangulation with a garrotte doesn't fit into any accident scenario, that would only leave the head bash as the accidental injury... I believe that the head wound is simply too big, and done with such force, that it must have been somehow deliberate...
I've recently been wondering about premeditation, and it all been planned out beforehand, on cold blood. Some things could arguably point towards that, but again, to me personally, it doesn't quite fit. Amongst other things, assuming that both parents were involved to some degree or another, why would Patsy enter JB into another future pageant? Why would the Ramsey's have planned a holiday the next morning? Also, if the idea in advance was simply to kill/silence her for some reason, wouldn't the head bash have been enough in itself? Or even two bashes if the first one didn't do it completely? (Sorry to sound horrible). But, then, why bother with all the cord/duct tape etc?
This has got me wondering if it could lie somewhere in between? Some type of unpleasant/abusive situation that was being inflicted on JB that night, with at least the knowledge of both Ramsey's, if not both being actively involved... I'm not sure exactly what, but whatever was happening may even have happened before, or maybe it was the first time. It wasn't meant to lead to her death, but something went wrong and it did... The head bash, strangulation etc were all part of this scenario somehow, plus used for extra staging too, as the Ramsey's needed to make it look as if they weren't involved?
Only my own recent thoughts, and probably completely wrong?
