Everyone has a right to protest. Not everyone is so smart about it. I'd really like a better explanation linking the Iraq war to global warming, but it didn't really come despite the cute polar bear suits and the ever present Code Pink. (See the video.)
But, you out-of-towners just don't get the security challenges at the Capitol. Not even thinking of terrorism, there was a crazy man who shot two people and killed them, including a Capitol policeman. These folks work very hard, are nonpolitical, and are just trying to keep people safe. Sure, the Capitol has real symbolic significance. But Monday morning? Staffers (not congressmen and women) are rushing to get to work, and you're blocking traffic with a nonsensical chant?
Please . . .
