DG: I don't think the man in the robe was Mr. Marr. I'm guessing (and it's only as guess) that he was a member of the rally and was conversing with the police regarding the interference from Mr. Marr's loudspeaker.  Perhaps he was signing a complaint.  I don't really know.  However, he does look like a Buddhist monk...not Mr. Marr and, quite likely, not a buddy of Mr. Marr's.
