Thanks Fred, so much of that interview really resonated with me, like the futility of debating CT Zealots, Markham's 1:06 is set in stone but her Oswald identification was the result of a screwball, the Roberts "about 1PM" estimate means
exactly 1PM, Roberts saying "just long enough, I guess, to go in there and get a jacket and put it on" is totally refuted by her "maybe not over 3 or 4 minutes" which BTW is usually interpreted at 4 minutes, but in reality using the term of "minutes" is just a figure of speech.
Also fascinating was the computer generated recreation of the Tippit shooting location and the following attempted "suicide by cop" in the Texas Theater, I have long held the same belief, Oswald's Walker letter where he says "If I am alive..." was how he thought his life would end and of course his Russian suicide attempt he outlined in his "Historic Diary", Oswald was willing to die for cause and/or just had a death wish.
For anyone who is a student of this assassination, I strongly suggest to watch this video and at least the Tippit reconstruction @56:00 and witness the culmination of Dale's accumulated decades of reasoned research.

In the computer graphics aided recreation all the major players and their locations are clearly represented, here in this one small segment we see the positions of Oswald, Tippit, Benavides, Markham, Scoggins cab, the Davis sisters house, Jack Tatum, etc.
