No doubt it's been rehashed a million times. Going back to the only visual evidence we have of the perp is vital.I know this thread is 2000+ pages but yes, this has been dissected over and over and yes, there are a lot of strange mannerisms/choices in it.
Also note that he is carrying what appears to be a semi auto that is almost falling out of a mismatched pistol holster. (may not be an actual live firearm, no way to know).
The Walmart exclusive backpack also had reflective strips on it which are notorious for glowing on IR (night cams). Some have speculated it was his "kit" - an assembly of abduction tools; zip ties, duct tape, tarp or plastic sheathing, rope, etc.
The bite light was additionally interesting because he used an approximation of DNA covering PPE (gloves, etc.) but then used a saliva DNA transferring bite light (yeesh!).
I agree his handling of the camera was very fumbled, as you suggest there would be a more direct way to deal with it. Indeed the footage offered up plenty of odd details.
I guess all the wi-fi jammer, internet connection, roof cams, alignment of the planets talk has me frustrated....lol
