I think this is where efforts to fight these problems fall down. They're almost all based on the assumption that the populace doesn't want this stuff to happen, but that the government pushes it through by abusing power, subverting democracy, etc.
But from what I see, this is not the case. Most Americans want this. Whether it's gun-wielding maniacs, drug dealers, or international terrorist masterminds, they feel unsafe, and want the government to help. They like heavily-armed SWAT teams available at a moment's notice. They like the government spying on every communication they can get their hands on. They like x-ray machines and body scanners in airports.
There is a sizable minority where sanity remains, but it is a minority. I think that efforts to fight these problems need to recognize this, and realize that you have to convince the people as your primary action. Fighting the government won't help, because the people will insist that these things be done, as long as the majority feels this way.
No, I don't know how....
