The current trend is clear. The politicians think government surveillance of people is good but not the reverse. That is why you can get tossed in jail for recording police misconduct. Notice the crack down on government whistle blowers even ones that report misconduct. Homeland security locked down a major metropolitan area to catch one criminal and the people cheered. Large numbers of people still believe that additional surveillance will make them safer. You can count on more surveillance, less privacy, and more restrictions on the use of personal recording devices. That is the trend until attitudes change.
