Not convinced in some of the “No bag” pics, he could have it in his hands. The shoulder gym bag is definitely there for the other guy. But it is the same packpack and looks full.
The white guy with the beard doesn’t appear to have a heavy backpack.
The guy next to him has the same shoes, same pants, and has a pack too. The guy next to him also has some kind of credentials too. I’m thinking this is some kind of uniform. Like police or military or something.
