Between Sept 2011 and Sept 2012, more than 90 journalists (both independent and mainstream) were arrested while covering Occupy protests in the U.S. Removing journalists and citizen journalists from the scene seemed to be a strategy because acts of police brutality -- when recorded by citizen journalists and ubiquitous cameras & cell phones -- led to more sympathy and activists for the movement: for example, in NY City and at University of California, Davis. Like in the 1960s, the federal government built a large surveillance apparatus to spy on Occupy activists.
And the surveillance of social movements continues into the present.
"THE MAYOR'S AFRAID OF YOU TUBE": In October 2011, hours after New York City authorities made a last-minute decision NOT to clear protesters from the original Occupy Wall Street site in Lower Manhattan, filmmaker Michael Moore said this to MSNBC's Lawrence O'Donnell (begin 2:54 for context):
"One cop down there actually today. I asked...'Why don't you think the eviction happened?' And he said, 'Cause the Mayor's afraid of You Tube.'...The power of the new media, the media that's in the hands of the people -- that those in charge are afraid of what could possibly go out."
