Selma Reenactment?

When is a reenactment NOT a reenactment? All weekend I've heard and read about the "reenactment" of the march across the Edumnd Pettis Bridge in Selma, but that's not what happened. It's also not truly a "celebration". The Montgomery Advertiser had it right when Alvin Benn described the event as "a commemorative walk" across the bridge. A reenactment is just that, and for there to be a reenactment of Bloody Sunday you would need, well, blood! At least fake blood, and actors playing the role of Alabama State Troopers with batons. The more I think about it, the more I see why organizers decided on a commemoration as more appropriate than a reenactment (no matter what some reporters call it).
