Why do Jake's Guy and the guy next to him look like they are both wearing hoodies? I don't recall anyone wearing hoodies in 1963. Are they time travelers, in which case they perhaps would have been invisible to the others on the bridge (but not to the camera, which is not fooled even by time travelers)? I congratulate Jake for finding an image where, yes, I can actually see a guy, and yes, he actually does seem to be holding something. It looks like the way a press photographer would be holding a large format camera, but why would time travelers be using large format cameras - unless, perhaps, they are time travelers from the past?
Edit: As it turns out, hoodies date to WAY before 1963. So much for the time traveler theory. The two guys do look spooky and vaguely demonic, but I'll let it go. I have no idea what the device is, but isn't a scope on a rifle. It appears to be attached to the front of whatever he's holding, like a telephoto lens on a camera.
