The D.C.-based libertarian blogosphere is up in arms today over the Saturday night arrest of D.C. resident Brooke Oberwetter at the Jefferson Memorial. The story goes like this: a group of about 20 nerdy libertarian wonk types gathered at midnight on Saturday for a sort of flash mob at the memorial to celebrate the birthday of their favorite founding father. They gathered at the memorial, each with an iPod, to dance together while wearing headphones.

In the video above, you can watch the group as they quietly danced around the memorial (which, to be clear, is open to the public 24 hours a day, according to its web site). A U.S. Park Police officer can then be seen approaching the dancers and telling them to leave.

The second video, posted below, shows the dancers arguing with Park Police officers about why they’re being asked to leave. They say they were quietly dancing with headphones on to celebrate Jefferson’s birthday, and that they weren’t breaking any laws (which, as far as we can tell, they indeed were not). Toward the end of the video, you can see Oberwetter, 28, being handcuffed and taken into custody. Where was Kevin Bacon when they needed him?
