I believe Shelley and Lovelady were just a couple of dolts who lied for no good reason..... as you said "pointless and bizarre"
You couldn't be more wrong Walt.
The lies of Shelley and Lovelady are co-ordinated and take place over various statements.
In their same day affidavits both men conveniently omit that they went to the west of the building and entered through the west door.
Both men give the distinct impression they went back in through the front entrance immediately after the assassination.
In their WC testimonies both men tell the outrageous lie that Truly and Baker didn't reach the TSBD steps for at least 3 minutes. This delays their arrival at the west door 5 to 7 minutes after the assassination.
We now know that Lovelady didn't even enter the west door at that time and, as revealed in his HSCA interview and the films of Hughes/Martin, did not enter the TSBD building for 20 to 25 minutes after the assassination.
This leaves Shelley lying his arse off in his WC testimony. Note the use of the word "we":
Mr. Ball: What did you and Billy Lovelady do?
Mr. SHELLEY: We walked on down to the first railroad track there on the dead-end street and stood there and watched them searching cars down there in the parking lots for a little while and then we came in through our parking lot at the west end.
Mr. Ball: At the west end?
Mr. Shelley: Yes; and then in the side door into the shipping room."...we came in through our paking lot at the west end."
Here, Shelley is saying both he and Lovelady entered the building through the west door.
Mr. Shelley: I saw Eddie Piper.
Mr. Ball: What was he doing?
Mr. Shelley: He was coming back from where he was watching the motorcade in the southwest corner of the shipping room.
Mr. Ball: Of the first floor of the building?
Mr. Shelley: Yes.
Mr. Ball: Who else did you see?
Mr. Shelley: That's all we saw immediately."That's all we saw immediately"
Here Shelley is still insisting he and Lovelady were together when they first entered the TSBD. More than that, Shelley is speaking for Lovelady as to what he saw when he entered the building. How does Shelley know that's all Lovelady saw as well, unless it's a co-ordinated lie.
Mr. Ball: Did you ever see Vickie Adams?
Mr. Shelley: I saw her that day but I don't remember where I saw her.
Mr. Ball: You don't remember whether you saw her when you came back?
Mr. Shelley: It was after we entered the building.
Once again, Shelley is peddling the lie they both entered the building together.
If you think this is just two morons lying for no good reason you are entitled to that opinion but I most certainly do not share it.
