Thanks for clarifying!
Ok folks, I have a possibly new or new to me idea I wanted to bring up. I haven't seen it posted anywhere so maybe it hasn't been considered yet?
Any chance BG was sporting a headset as he crossed the bridge? Have a look at the still frame I found and look at the areas of interest I've outlined.
You may see what could be headphones. Eg: gamer style ones that fit over the ear and may sometimes resemble ear muffs. These may be wired or wireless. You may also notice what may be a mic on a boom arm just infront of the mouth area.
It's NOT a fact that this is what it is. It's merely a possibility I wanted to bring up as I haven't seen it suggested anywhere yet and I want to try to encourage new discussion anytime I can! What are your thoughts on this idea?
Delphi Murderer Closeup that's the link where the photo came from. It's I think frame 47 or 48 of the series of stills from BG crossing the bridge released originally by LE. I don't know who broke it into still frames or I would credit them accordingly.
