There was a demonstration on the Green last week. I didn't see it myself, but photos have been showing up on Facebook. The issue in question is the controversial presence of the potentially centuries-old whipping post on the newly renovated Green. While many people have forgotten its original purpose and saw it as an innocent piece of history, in use as a bulletin board for centuries, others clearly recognized it as more than just a public notice board.

The demonstration was performance art, as you can see from the photo, one of several circulating on Facebook right now.
