I've explained this before, tin foil hats actually serves as a radiator for your brain wave, which makes it easier for the governments brain wave interceptor satellites to pick up your brain waves. What you need to block these satellites from reading your brain waves it a hat made of randomly arranged organic fibers. Cow dung is the best thing to use. Go to a cow pasture, find a fresh pile, and place if one your head. Your new bullshit hat will protect you.
Seriously, the idea that the government can arrest people and hold them indefinitely without a trial concerns me. But the article is heavy on sensationalism, and light on actual information. The Supreme Court ruling as a procedural ruling about the merits of a certain case, not a ruling about what the government can do.
