ITA. I think on Nov14 after Dr. Lee looked at the car and told JB in no uncertain terms that there was a dead body in the trunk, JB went to KC and told her to come clean. He then got word back to the A's and the PI's and had the PI's go out and video tape the general area so they could see if the bag was visible now that the vegetation had started to die off. I don't think it was taken to support a defense of "look, the body wasn't there on 11/15 so my client couldn't have done it" but was taken to assure themselves that the body was hidden well enough and wouldn't be found. You'll also notice that this is about the time that MN quit. I speculate that he found out that the A's knew about the location of the body and that they were going to keep quiet about it and he didn't want to be a part of that crime so he quit. Everything was going along fine. The A's were still able to play the "Caylee is still alive, please send us money to help search for her", they could still pretend that KC was innocent. Then along came Roy on 12/11 and screwed their plans all up. Now everyone's getting nervous about being charged, they're asking for immunity and lawyering up and they're just waiting for the other shoe to drop. The PI that has the video figures he better leak it to the media and take the stance that "I didn't know the reason they asked me to video tape that area. They just told me to go to Suburban Dr and video tape the swamp on the south side of the road"
***the above is purely speculation on my part, but like any puzzle, if the pieces fit.....*****
