You know, for as much as we like to talk about freedom of speech as an inalienable right, I think it ought to be one of those "rights" that you can lose if you abuse it too much. Like, criminals can already lose their rights to own guns, and no one who matters, even the most hardcore second-amendment nuts, will argue that it's unfair. Life, liberty, and property? Fines are the most common punishment for minor offenses; prisons exist for a reason; and if someone is a clear and present danger to the lives of those around them, the cops can and will shoot to kill, and the only regrets anyone will have is that they couldn't be taken alive to find out what his freaking problem was.
So why, when someone is found guilty of spreading dangerous lies about innocent people to the tune of over a billion dollars, can they not just be forcibly silenced so they can't do any more harm?
