Seems like a perfectly reasonable question.

The worst evasion here is you avoiding answering how the man you are labeling Shelley has an obviously too stocky body to be Shelley...

After Oswald was brought in from the theater, everyone gathered inside the office of Capt. Westbrook.  This office is where the officers filled out their arrest reports

True, that's also where they marked pieces of evidence, regardless if they ever were in the chain of custody or not.

Inside this office was Westbrook, Barrett and Oswald's wallet (with Oswald and Hidell identifications inside and taken from him by Bentley during the car ride from the theater to headquarters).

Really?

The sequence of events disagrees. The officers who drove in the car with Oswald, left him in the homicide bureau, with some uniformed officers.

Only minutes after Oswald had been brought in, Guy Rose started working and the first thing he did was talk to Oswald. When he walked into the room, somebody gave him a wallet and told him it belonged to the suspect. That's the wallet in which Rose found the Hidell ID.

Now, if Oswald's wallet was in Westbrook's office with a number of officers, as you claim, how could Guy Rose be given that same wallet?

Perhaps, if somebody needs to think about it, it's you.

If you read what they all said and wrote, they showed up in the basement of the Municipal building, and brought Oswald up the back elevator to the DPD offices on the third floor. The party first went to the Homicide office, where they deposited Oswald and the wallet with Baker and other members of Fritz team. Hill and Baker conversed about possession of the revolver, the result being that Hill kept it. Then the arresting party proceeded to the squad room in the Personnel office. Bentley and Lyons went to the hospital to have their injuries examined, while the rest of the party set to writing reports. At some point after Bentley and Lyons left, Westbrook entered the squad room, saw the revolver lying on a desk, and sent for Lt Baker to come get it. At this point, Hill, Carroll, and McDonald put their initials on the weapon and turn it over.   

The fact that you have to put several "ifs" into your scenario means that nothing you are saying is an established fact. It's simply your guesses.
