I don’t know about that. These two are wearing the same type of hat just different colors. They are together yet keep the same amount of space between themselves, never talk or look at one another, yet are definitely together walking the same route.
As is the girl following them. She is almost exactly the same distance based on the sidewalk squares. The backpack shown in the explosion photos is black and has silver on black stripes on the straps. His bag is gray with no stripe on the strap. Did the explosion change the color and straps that much? And why do the feds think these two are together? Also if you were going to quietly drop your bag and walk away wouldn’t you be carrying it like the second guy where you could just slip it off your arm rather than having to squirm out of it to put it down?
What about guy in burgundy cap. Has backpack and a tote of some sort?
