Air travel locked down by armed guards, searching and demanding identity, now trains. What's next, buses? Then what, UK levels of CCTV, face recognition motorway(freeway) cameras? Oh yeah, we Brits have those. What is the limit here, can we expect check points on roads? Add to that comprehensive, industrial slurping of all electronic data and metadata. Almost forgot, a mostly compliant and controlled media and a political class who knows the NSA have all their personal data from 10 odd years. Damn, another one.... a huge military intelligence industrial complex which "donates" a fair amount of money to both US political parties, and of course expect nothing in return. (BTW, isn't the military the biggest and most powerful union in the US?). Freedom of movement, gone. Freedom of expression, monitored. Political freedom and independence, bought. Anything left? Is picking the channel on a TV or chose our clothes all the freedom we humans need? Heh, I could even make an argument that those are also controlled, at least highly manipulated.
At times like this I want to kick Godwin in the nuts.
