Once you turn your hard drives over to a government entity and they have your computers, they essentially have access to the newsroom.
The government appears to be going very aggressively after these types of leak cases, ... and when reporters are involved, I'm just gritting my teeth.
I'm not aware of any previous government attempt to retrieve such material. Librarians and historians are having a fit, and I can't imagine a bigger chill to journalists.
People clearly think that their federal government is more secretive than state or local governments. And they are probably right. It has become more difficult to get information out of the federal government.
What these open government laws do is break down that wall of government secrecy so that everybody knows what's going on. A democracy can only function if we have information. You can only have oversight of government if you have information.
