I do Not see the "bend in the wall" on the photo you posted.
You do know there are 2 walls there? (1) the long wall the people are seated on in the photo you posted, and (2) a short wall running between the Tall Stone Monument and the thick tree on the (R) in the photo you posted. This is why the Croft Cone is incorrect. Based on that cone, we should be seeing that Tall Stone Monument in the Croft photo. You walk down to the very end of that sidewalk that runs behind the wall the people are seated on, and you can reach out and touch that Stone Monument. We frequently hear about how "small" Dealey Plaza actually is. The Tall Stone Monument, the Wall people are seated on, and the RL Thornton Sign were close together. Of course, the RL Thorton sign was removed extremely early on. Over time, this destroys those Land Marks very short distance from one to the other. Either the Croft Cone is inaccurate, or the Croft photo has had the Tall Stone Monument removed/cropped from it. And Croft did have issues with the FBI concerning his film.
