From this view, the bag has been dropped by suspects in right red circle. White guy with bad is looking at them like "Hey, why'd the hell you drop this?" He probably takes the bag and drops it over by the wall.
It looks like the two arab guys have the bags and the white hat drops his. The white guy with the blue/reg shirt seems to be looking for the owner of it after they drop the bag (not shouldering it, just holding it). If only there was video showing their interactions.
