Yet, they were harmed, and the government knew it. Years after he died, longtime FBI boss J. Edgar Hoover was quoted boasting of the success of this program. The harm existed in the pause or second thoughts that protesters gave to their contemplated behavior because they knew the feds would be in their faces -- figuratively and literally. The government's goal, and its limited success, was to deter dissent without actually interfering with it. Even the government recognized that physical interference with and legal prosecutions of pure speech are prohibited by the First Amendment. Eventually, when this was exposed as part of a huge government plot to stifle dissent, known as COINTELPRO, the government stopped doing it.
Now, the government fears the verbal slings and arrows of dissenters, even as the means for promulgating one's criticisms of the government in general and of President Obama in particular have been refined and enhanced far beyond those available to the critics of the government in the 1970s.
So, what has the Obama administration done to stifle, or chill, the words of its detractors? For starters, it has subpoenaed the emails and home telephone records of journalists who have either challenged it or exposed its dark secrets. Among those journalists are James Risen of The New York Times and my colleague and friend James Rosen of Fox News. This is more personal than the NSA spying on everyone, because a subpoena is an announcement that a specific person's words or effects have been targeted by the government, and that person continues to remain in the government's crosshairs until it decides to let go.
