are these demonstrators being handled by
Having watched how these things usually go down. Here's a word to the wise. If anyone sees Victoria Nuland handing out cookies to the demonstrators...that's a very BAD sign.
NOTE: Those who are blindly "following orders" or are being paid to demonstrate against President-elect Trump should use their time more wisely by watching this video. An interview with journalist and documentary film maker John Pilger. It's called "No one to vote for."
