I don't necessarily think it happened the way the video showed; however, it does show that it "could have happened" and shows the time frames of how long everything could take. But I will try to answer as if I believe it... and will answer what I can...
1. Kuss Rd is walking distance from the Avery lot. Wouldn't have been hard for anyone to do, including Bobby.
2. There is evidence that the burn pit was not the primary burn site. The fact that there were bones found in at least one barrel behind the Dassey house, and bones found in the quarry owned by Manitowoc County, indicate that the burn site could have been in barrel's, in the quarry, and some moved. IF it was Bobby, Bobby had from the 31st until the 4th/5thish to burn the body, and move the bones. If the body was burned elsewhere, say the quarry for example, and LE wanted to "help" the case against SA, this is where I believe they found them and moved them. The investigation of the bones was the most mishandled evidence in this case IMO. There are no photo's of the bones in situ, no gridding, and even the States expert, Ertl, said in an email to Fassbender that he did not take any photo's of the bones because it was obvious it had been altered before he got there. That is telling IMO.
3. I'm not sure why you are assuming that LE needed to make a connection with Bobby to have found and planted the license plates? Maybe I missed something in the video/theory? I think it's very possible that Bobby moved the RAV4 himself, and/or put the plates where they were found?
4. The key. The key was the valet key, not the main key. The other part of the lanyard was found in the middle console of her RAV4. Where are her other keys? Out of all the evidence, regardless of whether SA did it or not, I do believe that the key was planted by LE. Possibly just to ensure a reason to arrest/convict Avery.
5. Roland Johnson. He owned the trailer, and he owned the gun. His testimony can be found here:
http://www.stevenaverycase.org/wp-c...rial-Transcript-Day-19-2007Mar08.pdf#page=148 He says he shot the gun all over the yard, around the garage, and at the door of the garage. That would make it pretty easy to either kick or move a spent shell/bullet into the garage over the years. He lived there for many many years. He said he never cleaned up the spent shells/bullets over the years either. Would make it pretty easy for LE to find one to plant some evidence on too, wouldn't it? It wouldn't be like it was an anomaly there.
6. The quarry... or burn barrels? seems like KZ has some evidence that there were more than just the pelvic bones that had cut marks and it's possible that she was indeed dismembered, which only makes sense if she was burned in a barrel. I guess it's possible it could have been done in a barrel at the quarry and moved later too?
Like I said, I don't necessarily believe the video. I just can't see her pulling over for someone guy following behind her. I have always wondered if someone hit her front end (the damage to the front of the vehicle), causing her to pull over and when she was at the back of the RAV4, she was hit with something (the blood spatter on the back door and the missing RAV4 tool from her kit). What I did like about the video is that it showed us just how quick this could have happened. How quick she could be there and leave... how SA went out, back in and out of his trailer, how he
could see a vehicle turning at the corner by the highway, how Bobby would
not have been able to see TH from where he said he did, the video of going down the road and going to Kuss Rd. It sure gave me a perspective that a google map just couldn't.
