You've been completely unable to demonstrate your contention that the motorcycle officer in the Darnell film is not Haygood. When we strip off your misconceptions, your misunderstandings, and your miscontruals, all we are left with is a base assertion that "Haygood didn't explicitly say he was in the rail yards behind the knoll." Which isn't really an argument. So now you want to shift the burden of proof, and declare yourself the victor. A quaint strategy, but the rest of us see right through it.
The newly discovered Darnell Film Snippet which shows the Elm St Extension jammed packed with people, while at the same time Officer Harkness standing alongside the "One Glove Cop" inside the railroad yard, blows the above blah, blah, blah, all to hell. Officer Haygood made a documented 12:35 PM police radio transmission from his motorcycle at the Elm St curb near the Triple Underpass. Officer Harkness made a documented 12:36 PM police radio transmission that he was headed to the TSBD with eyewitness/Euins in tow. So at what time is this newly discovered Darnell Film Snippet happening? 12:38 PM. That "One Glove Cop" is not Officer Haygood. The timelines of officer Haygood and Officer Harkness make this crystal clear.
