It's possible that Adams was mistaken about seeing Shelley and Lovelady but I doubt that she was. She recalled it on two separate occasions.
Okay, can you find a way that she possibly could not have been mistaken when we know, from their testimony, that Shelley and Lovelady were outside the building when the shots were fired and did not return to the 1st floor until 12.35, just prior to the building being sealed off.
We also know that Victoria Adams re-entered the building through the main entrance at the front, after hearing a DPD radio message at 12.36. She went up the stairs to the 2nd floor, walked through the office space to the freight elevator at the back of the building and went up to the 4th floor with two police officers.
I take it that you agree that if it is physical impossible for two people to be in eyesight of eachother at a particular time, it is impossible for one of the people to have seen the other, right?
When and where exactly do you propose Adams could have seen Shelley and Lovelady inside the building?
