We won't be getting into broad Tea Party politics, but the fact that they, of all people, were singled out is telling.
I've seen official scenarios involving "extreme right-wing militias" and white nationalists, but that's a bit more broad. Specifying a specific and diverse group with no history of threatening violence, stockpiling weapons, or conducting paramilitary exercises smacks of having a petty political ax to grind.
I don't imagine the powers that be will be taking this very seriously.
Sometimes it’s nice not to destroy the world for a change.
