You spend 45 years, 1945-1990, giving away your 4th and 5th Amendment rights and protections because the Government tells you they're fighting off some amorphous boogeyman. You didn't get anything in return for the rights you frittered away, you just gave away your freedom. Dirt cheap. Now the Government has made you the boogeyman, they're coming for you, and you can't figure out how they got all that power. You did it to yourself.
Too late to wonder about it now, you're too busy scrambling to preserve the few freedoms you have. Seems to me you got played for the fool.
