Storming the White House
Word is that Moonbats International plans to storm the White House on March 15, accompanied by Michael Moore. (Not likely--Mike just would like the publicity that comes from making the claim. He's going to be busy doing his corporate taxes that day anyway).
In past years, stuff like that was a way to get quick publicity. Getting arrested outside the South African embassy was quite the fad in the early 80s. Get arrested, booked, and released, and then the prosecutor will drop charges. Or if you get really annoying, judge might impose a $50 fine. I rather suspect that, post 9/11, an attempt to actually force your way into the White House might be met with a more vigorous response. Secret Service isn't famous for wimping out when facing something like that, and probably has a bunch of crowd control tools that need testing. Anyone getting past that might just face much older tools, such as the 7.62 NATO.
