I'm not sure if it is a wristband or a bracelet, but look at David Bailey's wrist in the photo here:

and compare it with the shooter's wrist here:

TChad, I think I’ve figured out the answer to my initial question about the photos in posts 1, 2, 3 & 8. Upon closer inspection, i.e. I enlarged it much further, and it appears that the “red circle” surrounding the shooter’s hand/gun covers the beads on his left wrist, which are apparent in the additional photos you posted. I can, barely see a white bead on either side of the read line in the lower left of the circle.
Thanks.
