If you are from the US, be aware that even United States spies on its citizens, and recently-activated social media screening is just another step towards it.
sorry to break it to you some citizens can be traitors relaying on the "I know his people" and he's a good chap belongs to the right club does't work as a vetting procedure as we found in the UK with the cambridge 5 and others
I agree, but this is a slippery slope, and be mindful that warrantless surveillance is technically illegal (or not, i don't know what patriot act brought these days). It's a slippery slope because there is no end to it. It starts with surveillance - which evades privacy, then comes your freedom of speech, then your freedom to choose.
Oh I agree on warrantless wire tapping the one of problems with the states is they don't separate the Police role of the FBI from is Security / Contra Espionage.
