I don't think you can find anything out on invisible gun guy from the shots available as there's no face and a plain white shirt
He was pulling on his hands after putting the phone away but it looks to be a nervous habit not some home plate signaling the way the guy behind charlie did

Look at the zoomed in version, he's just a fidgeting zoomer as far as I can tell, maybe taking a cue from the question about firearms
It's a lot less damning when examined more closely IMO

>Looks more like white shirt (no face) is shooting an invisible gun at kirk.
A very sophisticated hit.
