This video has good information on the extent of surveillance in society, Though Corbet talks about US politicians, I think ifs safe to say this is all over the west. Yes, big brother is always watching, but more importantly does the US or any western country need a NSA? I think not, if you (meaning the government or special interest group, truly care about my opinions or ideas, you can dam well ask me). The Reich Was Right!!!
