It's baffling to me that country like America with strong 1st amendment and freedom of speech culture has people who think a journalist should be put in prison.

So, now, a whistle-blower needs to have strong anonymity and privacy to pass information on, and the newspaper needs to be strong enough to protect its journalists. And when this might mean that the editor goes to jail (contempt laws?) that's a lot to ask.

But would any sane government push things that far? Locking up the editor of a newspaper for not handing over the name of a journalist?

(I'm about to web-search, but have any American journalists been jailed for not giving up the names of their sources?)
