You left a factor out.
Maybe R dressed up as F, but wasn't necessarily the person who was on the interview. If, and it's a big IF, he is alive, he would not be interviewed yet, but may show up in a costume to be present at the rally.
Previous anon showed "Caroline" with a black hat and presumably F next to her; then later (same rally) with white hat and presumably R next to her. Not saying it's him, but stranger things have happened. Its not like he's going to whip off the costume mid-rally.
It may not be true… but what if it were? WOW!
