It is generally understood that the plotters of the conspiracy went to Lovelady & Shelley and got them to lie and say they left the front steps 3 minutes after the shots because they were trying to doctor Victoria Adams' testimony in order to push it back 3 minutes in order to give Oswald time to make it down the steps...Adams was a problem because she and Styles did not see Oswald running down the NW steps...The plotters knew this so they went to Lovelady & Shelley and got them to push their times back in order to make Adams look stupid...They hadn't considered anyone closely examining Couch/Darnell at that time and seeing Lovelady & Shelley fast-walking up the extension revealing the true time...In 1974 Dallas reporter Dean Glaze got Shelley to admit that he was CIA...The rest is academic...Shelley was a major part of the conspiracy in the Lobby and guided Armstrong's "Harvey" out the back after being stopped at the front door by a cop...That is why Shelley was mentioned in Fritz's notes - but only in the context of being out front in the Lobby with Shelley 4 or 5 minutes after the shots...Kamp misrepresents that as being out front with Shelley during the shots...Kamp is a liar...
Couch/Darnell is film evidence anyone can see with their own eyes...Lovelady & Shelley's 3 minute lie is no valid substitute for what is more than obviously shown in Couch/Darnell...Stubbornly repeating it over and over while ignoring the plainly-visible evidence is not a credible research practice...Once you've proven Lovelady & Shelley are the men on the extension then the man in front of Calvery on the steps automatically becomes Molina...
