I keep hearing people say that something must be done quickly, "before the United States becomes a police state." Um, I hate to break it to you, but you're a little late.
What exactly do Americans think distinguishes this place from a police state? In a police state, state enforcers can randomly stop you and demand your papers. Like they do here (via "stop and frisk," "regulatory checkpoints," "border checkpoints" not at the border, etc.). In a police state you can be detained indefinitely without being charged. Like here. In a police state there are sadistic, power-happy jackboots everywhere, constantly looking for reasons to harass, rob or kidnap non-violent people. Like here. In a police state, the state's thugs literally get away with extortion, assault and murder. Like here. In a police state, you are treated like a criminal until proven innocent (and then still treated like a criminal). Like here. In a police state, everyone's communications and actions can be monitored and recorded. Like here. In a police state, you need the permission of the ruling class to do almost anything. Like here.
Let's clear up a few stupid assumptions that some people seem to make. In a police state, often a huge percentage of the population APPROVES of the situation, at least at first. In a police state, there is still "rule of law," there are still courts and administrative procedure, etc. In a police state those in power still pretend they are PROTECTING the people by way of their fascist tactics. And in a police state, a lot of people are still stupid enough to believe it. In a police state, MOST people do NOT get harassed. The fact that YOU grovel and kiss the ring, and as a result, haven't been directly threatened by state mercenaries, doesn't mean this is a "free country"; it means you are a good slave. And that is why police states happen: because members of the general public not only don't do anything to resist it; they don't even NOTICE it.
If you're worrying about the U.S. becoming a police state, stop worrying. Because it already did.
