I try to be careful to use imo (in my opinion) or to state "I think" or "I believe" when discussing cases. Granted, there are times I slip up.
IMO...the critical part of the timeline is something they would need to get straight not who ate breakfast and when. Yes, it is my opinion that what they did and when they did it over a period of a week prior is part of the overall picture...but not the critical part. It begins and ends with the last time someone laid eyes on DeOrr Jr. and when they discovered him missing and how it relates to everyone else...IMO.
I just don't think the specific time you're talking about can even possibly be answered in a meaningful way without the answers to those other questions. But, if THAT'S the ONLY part of the timeline Klein is also talking about, I don't see how he could have 90% without ever speaking to IR.
And, if that portion is all that's critical, then why do we have over 16,000 posts, most of which talk about everything BUT that?!
