They already knew that.
You take kookiness to a whole new level. I hate to burst your bubble, [not really] but you haven't discovered anything of importance. Nothing you post here will ever see the light of day outside this forum. It's only make believe.
The problem with that is the Lobby, at the time of Lovelady's alleged sighting of Oswald leaving through the front door, was full of people 4 or 5 minutes after the shots...Including a cop...So your weak dismissal fails to account for the pressingly obvious and also fails to answer why that cop was never identified and never bore any witnessing of Oswald's alleged leaving through the front door...Your flimsy dismissal strains under the weight of the fact Oswald's alleged leaving through the front door was one of the most important events in the entire FBI and Warren Commission investigation...The Commission would have loved to have a confirmed witnessing of Oswald leaving through the front door from either Lovelady or the un-named cop...Additionally, the cop told Oswald to step aside and wait...So Oswald's disobeying that order and leaving anyway is something the Commission would love to show as matching a fleeing presidential assassin...But, no, that's not what happened and the HSCA and Warren Commission sheepishly avoided those witnesses and did ZERO investigation of Oswald's leaving the Depository...What is left out of your flimsy dismissal is the fact a cop told Oswald to step aside and wait and your version has Oswald defying a police order right under his nose and walking out anyway...Whether you realize it or not I'm cracking the conspiracy here...The reason the FBI and Warren Commission totally avoided Oswald's departure from the Depository is because they didn't want to step on any land mines involving this business in the Lobby and trigger anyone to talk...There was an explosive situation in the Lobby that was one step away from exposing CIA Shelley's leading CIA Oswald around the police cordon and out the back door...Knowing that any look in to the details of this might expose the entire plot they simply avoided it and committed a conspicuous lack of necessary investigation...Even if they assumed Oswald left through the front door it was still against the law for Lovelady to with-hold that kind of witnessing from the FBI in the original investigation...Overlooking that fact is less than honest...
Your flimsy excuse is stressed even further by the fact Buell Frazier, in his CSPAN interview with Gary Mack, told Mack that he saw Oswald exit the rear Loading Dock, walk down Houston Street, and cross over to Elm in the direction of the bus...So not only Lovelady allegedly held back but Frazier too...Gary Mack was one of the best knowledge-able people in assassination research and he was fully aware of the implications of what Frazier was telling him...Did Mack pounce on that admission by Frazier and probe him why he held back...Or review with Frazier the serious significance of what he had just told him?...NO...Mack changed the subject immediately and avoided any necessary follow-through on the consequences of the explosive information Frazier had just told him...Just like the HSCA did with Lovelady and their non-concern...
I've cracked the case here and put the puzzle pieces together in the Lobby...The Education Forum sells itself as THE going thing in academic research and assassination scholarship...It has no interest in this monumental break-through...It does its best to keep it off the board and keep the venue open to kooks and hacks...The new owner, Andrew Iler, locks threads as soon as he makes them so there is no member input...So what is that forum?...Who are its members?...And what is its true purpose?...
