I read the link, and the links within. I hate the fact that I'm about to defend the FBI here, but what I saw in the links is bloggers' circle-jerk (quite seriously--the links are self-referential) about the issue after-the-fact. I still haven't seen anything that looks like probable cause to score a warrant any earlier.
Let's be clear: I could acquire some land, build a ranch, put up walls around such areas as I desire. I could build a range, could invite whom I desire to join me, and could deny entry to any other. (Damn, this is sounding like fun; anybody want to kick in? It's like a gated community, but with a better gate, and a private range!) Frankly, I'd do it in half-a-heartbeat with a few select people (anybody want to cough up a few bucks?). I (we) could make it a policy to not speak to government agents (read: law enforcement, et al.) without a warrant, and certainly to deny them entrance to our (or, if I'm sufficiently funded, my) property.
Does anybody want to trash the Fourth Amendment and suggest that such shouldn't be allowed?
Everything I've read suggests that law enforcement was watching, but respected private property, civil, and constitutional rights until probable cause was evident. I stand by my position that this is a good thing. Freedom isn't certified safe. I'd love to have that isolated place (given a good internet connection), and should be free to do so, without interference from others; some would use the privacy for nefarious ends, but that doesn't mean we should put an end to privacy.
So...show me the PC that the FBI ignored and we'll talk; otherwise, it looks like things went off just right.
A lot of folks are willing to throw away those Fourth Amendment protections if it involves one of those "Mooselimbs"...forgetting of course that any government empowered and enabled to do that can flip the script in a heartbeat.
