It's a brave new world when thinking/discussing certain topics is illegal.
Look at what the Citizens Commission to Investigate the FBI found in just one two man office: over 40% of the documents concerned monitoring of political groups.
It's not armed groups that are dangerous, it's ideas. This is why people REALLY don't like Wikileaks, it exposes the truth and provides it for the people to judge in its raw and unadulterated form. Wikileaks poses only a threat to those whose power derives from deceiving the people.
