I've lost my key. But having lived here quite a while now, I have a fair idea I can jimmy the kitchen window. I proceed to do so, and happen to be caught in the act by the local bobby.
Now, just like every "freeman" on youtube tells me, I shut my mouth and tell the police nothing. I'm arrested, obviously, and events take due course. But I hold my "god-given right to silence" just like youtube tells me to.
When I stand before the judge and finally announce "your honour, that's my house", I'm basing my defence entirely on something I didn't admit during questioning. And I'd deserve to be treated like the idiot I was.
Obviously, I'd hope to never see this example play out in real life. But yes, withholding during questioning can very much work against you.
(for clarity; not disagreeing with you, but providing the analogue)
So I put to you a scenario. I've just been shopping for some housewares, and happen to have in my shopping bag a l large flat-bladed screwdriver. At the same time, the same object can be found about the person of another chap with a known drug problem and a history of breaking & entering.
Now, under English law, I'm doing absolutely nothing wrong, but it would be quite simple to confiscate the screwdriver from the chap with a history of breaking & entering, enquire about his business this evening, where's he's been, going, and even remand him for a more formal chat if his answers aren't convincing, or he's uncooperative.
In English law, this would be "Going equipped to steal"; the American reaction would be "Screwdrivers are illegal? since when?" Which is where we differ so wildly. It's often said that "possession is nine tenths of the law". In English law, Intent is nine tenths of the law. We really do depend on the judicial system showing some common sense, and protest when it fails to do so.
Which is exactly how this case works. If I encrypt my financial documents, my employer opts to encrypt my harddrive, a journalist encrypts their research, etc, this is prudent, and I would call any overreach against this "abuse of police powers" or "abuse of regulatory powers". But if a convicted terrorist has a cache of encrypted data, yes it's kosher for a court to demand the contents to further their investigation.
I'm quite sure all this makes me sound like an apologist; I believe nothing could be further from the truth. I do value my privacy, I do encrypt things "simply because I can", I'm disgusted by untargeted, dragnet surveillance, etc. But I'm also a realist, and there's a very simple problem here: Outrage at stories like this actually damages my position against such breaches of privacy. Internet Pitchforks are far too readily available, but they make us look like the tinfoil nutters. Where common sense dictates that an investigation is overreach, then yes, yell at the top of your lungs. But to protest a court order made during the investigation of a convicted terrorist - use some common sense.
I don't believe they actually require legal standing to board you if you're unflagged. Declaring yourself a no-man's land causes as many problems as it solves.
"we're not even based in your country, so your laws mean precisely as much as we allow them to"
They do have a footprint in Europe, which is why they had the Irish Data Commissioner crawling around for 3 months last year. Multinational means multi-juristictional too, something to do with having your cake and eating it.
My father was on submarines, and would come home from a 10-12 week patrol mildly short-sighted. He was ordinarily long-sighted, with a prescription to match.
We tell cube droids to 'rest their eyes' periodically during a 8 hour shift, by taking some time to focus on something that isn't 2 feet away (out the window, etc) exactly because this is a known issue. How did no-one assume that the same would happen on the ISS?
