A lot of the protestors on the far left have a history of violent protest, whereas there is no such history with FR protestors.
I had an opportunity to "Freep the Creep" my first time I went to the Saturday Freep at the White House. I got there before anyone else, and wasn't sure where to go, so I wandered around the perimeter of the White House with my sign and my costume (Clintonstein) looking for the right spot. Well, lo and behold, as soon as I neared the SW gate, a motorcade started to pull out - a Presidential Movement! I started to reach into my bag for my sign - and then realized that it wasn't such a good idea to be reaching into a bag for something with Slick's limo approaching and armed and nervous Secret Service guards all about. So sometimes it's best to not worry about the president and instead make your point to the media or fellow citizens.
Do yo have pics of you in your costume?
