There actually is a law forbidding any protest "device" in the gallery; the fact that she hid her t-shirt (unfortunately for her, not long enough) shows that she was aware of this, and so was the flake Woolsey, too, no doubt.
As I heard this, originally the news was she had a banner or something trying to open it. From the comments by Woolsey it sounds as if she was in the know of what Sheehan was wearing and thus complicit in her reckless behavior that ended up putting Sheehan in jail.
Now the question, what will be the outcome? Will she be slapped on the wrist, will folks have had enough. If so will the media go soft and say poor Sheehan which they have the possibilities are endless.
Glad to have no clue who Woosley is but should be removed from Congress.
