It's an Obama World Out There, Folks! 
NPS Director: Terrorism Made Us Shut Down the ParksThe National Park Service director told Congress on Wednesday that he had to shut down the open-air memorials on the Mall during the government shutdown because of terrorism, saying that closing them was the only way to protect them "in a post-9/11 world."
Director Jonathan B. Jarvis also said his agency had received intelligence showing an increased threat of danger since the shutdown began - though he would not tell two House committees what those warnings were.
Apparently that threat included domestic terrorists such as these members of the WWII Veterans Front.

It gets better:
MoveOn.org Petition Calls For Arrest Of Republican Leaders For SeditionOne outlet for that fury is a
petition from the progressive MoveOn.org that calls for the U.S. Department of Justice to arrest and try Republican leaders, including House Majority Leader Eric Cantor (Va.) and House Speaker John Boehner (Ohio), for "the crime of seditious conspiracy against the United States of America."
The petition
argues that "the House GOP leadership's use of the Hastert Rule and H. Res 368 to shut down the government and threaten the US economy with default is an attempt to extort the United States government into altering or abolishing the Affordable Care Act, and thus, is self-evidently a seditious conspiracy." (
The U.S. Code defines "seditious conspiracy" in part as any conspiracy "to oppose by force the authority [of the U.S. government], or by force to prevent, hinder, or delay the execution of any law of the United States." )
Well good luck with that. Of course if sedition laws were still enforced, most of the Democratic leadership would have ended up in jail during Bush's presidency...
