Actually my belief stems from the fact that I have been informed of the surveillance and given indisputable facts and documentation to back them up.
A recent example right here on this board: Look up a thread by Deus Ex Machina where he says that I am being watched from Dale.....which is the street behind my office. He also listed my initials. It was at the time he was promising an interview while alluding to hospitalization.
btw....I had some interviews while monitoring medication..... post accident....several years. The doctor stated that my mental health was essentially perfect.
Of course....that is before I discovered the internet.
I never even came close to mentioning the address of my office around here.
The people who refuse to believe that government does a great deal of surveillance are extremely naive.
I once watched a show where they documented the monitoring of JFK's sexual exploits (with quantity and duration etc.) well before he became anything.
I also have known some agents. One agency, in particular, really specializes in the planting of bugs. You could read my pm's and learn this of course.
