Supposedly these guys were runners. The winning time was 2:10:23. Assuming these guys are really great runners, what was their chip time? Did they have time to finish their run, suit up, and start blending in with the crowd by 2:35 clock time as shown in your blown-up picture? I wonder if they can be picked out in pics prior to the winning time, demonstrating that they didn’t run the race at all. There should also be pics showing them crossing the finish line.
IIRC from what I read earlier, the blue jacket guy, who is the one who is the distance runner, never ran the race. He had planned to, but got there too late. That would explain why he looks p.o.’d in the photos (assuming he is not a bomber).
