Dozens of people gathered across the street from the Federal Building in downtown Tampa on Friday afternoon to rally against the allegations that the National Security Agency is using the Internet and other technology to spy on U.S. citizens. The building houses Sen. Bill Nelson's local district office. According to organizers Sen. Nelson voted for the establishment of the Prism program. It was revealed last week that Prism, code name for a program surreptitiously collecting information via the Internet worldwide, was being used by the NSA. Participants from several organizations including Occupy Tampa, Veterans for Peace and St. Pete for Peace showed up for the demonstration.
