Blatant Intimidation and Control is not what the US Government does. If you want proof, compare the US handling of the Washington Post to the British handling of The Guardian. The Washington Post and New York times have been free to publish everything. The Guardian however, just had spooks smash their computers this past weekend.
The US affords the press freedom: freedom of speech, freedom of debate. There are no spooks here that are trying to shut anything down, anywhere. At worst, we have some secret conversation that happened between Lavabit's owners and the FBI. No one forced anyone to shut anything down however, most certainly not in this Groklaw case.
Abuses that have come to light are all under-the-table sort of affairs. Metadata collection is not technically data, and therefore isn't afforded 4th amendment protections. (See Smith v Maryland). Information gathered from the NSA technically can't be used in a prosecution case, so the DEA unofficially changes the story before it gets told to a judge (see Parallel Construction).
Some laws are working, but there are cracks in the foundation which is leading to an overall breakdown in trust. If anything, viewing the news recently has shown me that these agencies are very interested in following the _letter_ of the law, although not necessarily the spirit of the law.

History of the US is a sobering example, of the Government constantly giving up powers in favor of its citizens. Need I remind people of the Office of Censorship in 1940s, where Government agents read every single mail that was going across the mail system? Need I remind people of COINTELPRO in 1960s, the program the FBI used to spy on Malcom X and Martin Luther King Jr ?
The US Government has historically listened to the pressures of its citizenry, and changed. It is not the time to lose hope, but the time to make your voice heard. FBI and NSA, as intimidating as they are, are run by US Citizens first and foremost.
