Or not using certain words. Someone correct me if I'm wrong but I don't recall Klein ever saying the words campsite/campground and wonder why he avoids the use. He keeps using the general "on the mountain" or "near the mountain". The problem is though that if Deorr wasn't ever specifically at the Timber Creek campground then that would mean all POI's have lied and that just doesn't make sense.
Then again Klein has said (paraphrasing) you think you've seen it all and then a case like this comes along.
Of course, I can't help noticing that too. Unfortunately, I would venture a guess and say the reason has more to do with Klein than it has to do with DeOrr. If he doesn't confine his "theory/ies" to the campsite it gives him much more leeway. We KNOW (basically) what areas were searched and that nothing was found (from what we've been told early on). He wants to come across as having knowledge that was not previously known, but if he sticks to just the campsite area, he limits himself because he really doesn't, IMO, have any actual knowledge. Not at all sure if I've made that clear. If, after all is said and done it turns out LE believes there is no case to file murder charges or charges for concealing an accidental death, Klein can easily, IMO, weasel his way out by claiming the reason DeOrr hasn't been found is because the proper areas "on the mountain" were not searched but that's out of his control. Actually, it's kind of what psychics (IMO) do. A little knowledge, a little voodoo, and some believers. IMO
