I recently read a rather alarmed article about this act that claimed it was meant as another major weapon against the Occupy movement.
Then I read the bill and became a lot less concerned; the legal tools are limited to events and work of the United States President and others who are close to that person rather than general; it is still worrisome that disrupting government business/functions that involve such people could lead to such severe penalties though. I am not certain, but I think the "you lie!" outburst by Joe Wilson might qualify as disruptive, and while that outburst was a major breach of civility, I don't think it merits prison.
Am I misreading this? In particular, am I missing some ways this law could be used? Abused?
