You’re talking about Door 9 on the east side of AGR 6. The activities that occurred after Nicol’s 6:02 pm radio message, where he went downstairs to try to find Crooks, and met two LEO officers, took place outside of Door 13, on the northwest corner of the building, facing northward.
Those who deny that those activities happened deny all of the evidence describing it. The confusion between it and the Door 9 activities stems from a n erroneous entry in the AAR, which is a document full of inaccuracies, especially in the timeline maps.
Denying that Door 13 activities did not occur because you don’t believe the witness testimony because there is no video of it happening, is like denying the audio of shots fired because there is no video of the bullets traveling through the air. In an investigation, you cannot arbitrarily choose which evidence to ignore, it needs to be proven not to be authentic, invalid, or inaccurate before it is dismissed or treated accordingly.
But what do I know, I’m just a Certified Professional who has investigated various incidents for the past 30 years of my career, delivered trainings and a seminar on the topic, and published a few related magazine articles. How silly of me to even think about taking the evidence at face value. But I digress.
