Here’s my guess - the mysterious guy infiltrated antifa as an undercover agent and entered the Capital with them. He could have taken evidence away, including laptop(s). Antifa doxxed him but that would be his ‘cover identity’ (bartender) and not his real one. He won’t be found.
Either that, or I watched too many spy series when I was growing up!
Well, looks like the dude took his MOTHER to DC with him!
I saw an article with a British paper (The Sun?) where he gave a statement before the protest. I couldn’t read the article because you either had to register for free (I won’t) or pay (I won’t).
