Surveillance.
It always starts with a desire to be safe. And that comes from fear. It seems Americans today are afraid of more things than ever: pedophiles, guns, terrorists, lawsuits. Some news reports are ridiculous by foreign standards: teachers not being allowed to shake hands with students out of fear of sexual harassment allegations, boys suspended from school for drawing guns, bystanders not administering first-aid to accident victims out of fear of lawsuits, and of course the terrorism hysteria for which I have no words. I'm fortunate enough to have visited the US and have met mostly great people, but going by news reports the entire society seems paralyzed by fear.
I always thought of freedom as inversely proportional to safety. If you want to be perfectly safe, you'll never leave your house in case you catch a germ, get in a car accident or even slip on a banana peel. You'll never eat store bought food without first running it through a spectrometer. You'll want everything controlled, predictable, seen ahead of time so that nothing unexpected gets thrown your way.
I guess this is what surveillance is trying to do. Rather than accepting a level of risk as the price for being free and handling disasters when they do occur, we seem to be increasingly trying to avoid danger at all costs. And the cost seems to be freedom.
It's almost as if the author of the US national anthem knew this when he ended it with "land of the free and the home of the brave" (correct me if I got that wrong). Maybe he knew you couldn't have one without the other. I guess the brave isn't home anymore...
