The US government, still maintains a pretty strong protection of journalists. They will go after the leakers themselves, but rarely even attempt to make a journalist reveal a source, let alone prosecute the journalist directly for revealing secret information.
In fact, I say still, but this tendency has actually grown stronger over the last 50 years. It has, in my not-very-researched-opinion, grown stronger due to public pressures and effective civil disobedience. So, that heartens me. All governments screw-up, but some are screwed-up, I still don't think the US is one of the screwed-up - relative to the rest of the world and history - a LOT I wish they would do better.
