It's crazy, maybe it is the parking lot light casting shadows, but when he runs, it appears as though there is at least one flipper (scuba) on his right foot, almost as though he is dragging this foot a little.
His left arm flaps around and he seems to be holding on to something in the right pocket of the jacket with his right hand, then brings it out of the pocket and tosses it at the sidewalk. He then slows down -- I would think that LE has investigated every person who checked into that motel the evening prior.
He seems to hold his head back a little at the sidewalk, almost with an arrogant flick and then illustrates like he's home free.
His feet sure look bigger than 10/11 to me.
I agree with you -yes an almost arrogant glance. I wonder if maybe "spare" shoes are in the bag for a quick change and the medical or kitchen type garb is a a part of that. Maybe off for a break, follows someone into a store,buys a can or snack, follows and attacks,then races back in time for work?
