While it may be true that we're not living in a full fledged police state, that's just because the haven't taken off the velvet glove and showed their teeth yet. Make no mistake, the technology is in place, the jackboots have been delivered. They just haven't been issued with stomping orders yet
I understand what you're saying, but just don't see how "they" could do that on any wholesale basis, against armed opponents. Think about it. Nobody knows each of our individual AO's like us. We know every road, trail, rock, tree, hill and valley. We know all the structures and what they contain. A few good men with accurate rifles, moving from place to place, would at the very least slow them down to a crawl. Unless they were willing to wage full scale war against a civilian population (which would stop the economy and the collection of taxes dead in its tracks), there is no way they could selectively eliminate/apprehend enough "insurgents" to quell an ongoing rebellion.
Art's points are well taken, especially regarding Waco and Ruby Ridge, which were clearly police state tactics and nothing short of legalized murder. The powers afforded to government in the form of the Patriot Acts are also "troubling". I don't know whether RICO is rife with abuses of innocents or not.
To me, "Police State" means no knock entries, disappearance of people, suspension of due process, appropriation of private property, detention without reasonable cause, etc., on a wholesale large scale basis. I just don't think that will happen while we are armed. I think "they" (the wannabe tyrants) are afraid of an armed population, which is why this gun control incrementalism is so pervasive. Just don't turn over your firearms, NO MATTER WHAT crappy laws they pass. That's my philosophy.
