I believe the legal counter to this which is slowly starting to emerge is 'We're not ordering you to divulge your password. We're ordering you to decrypt the drive. We quite specifically don't want, or need, your password, nor do we care if the drive is encrypted with a passphrase, biometrics, physical token, whatever. We're just ordering you to decrypt it.'
Much like your 'papers' are immune to unreasonable search and seizure, but are subject to reasonable search and seizure, i.e. with a duly sworn out warrant and all that, so are your digital papers. I think this is the correct result.
I believe that, if the cops find a file in a locked file cabinet, said file being labelled 'Plans to murder my wife' and full of, well, plans to murder your wife, you don't get to have them declared inadmissible under the fifth; you get to refuse to answer questions like 'did you create these plans' and 'did you carry out these plans.' Seems to me that a directory full of documents, said directory being labelled 'plans to kill my wife' would be treated the same.
And part of the modern tribalism problems are because Europeans drew some lines on a map and said 'This is now a country, surely you two tribes that have been in conflict for countless years can now just get along, yeah?'
Note that Europeans have done this to themselves; WW2 was a direct result of this sort of crap after WW1.
A few years back, I wrote a letter to a teacher who was teaching my daughter's public school class, I want to say around grade six, the whole Columbus fairy tale.
It was a lovely letter, full of references to Washington Irvine, Ancient Greek origins of geometry 'literally, earth measurement' and experiments demonstrating the globular nature of the Earth, and surprisingly accurate diameter calculations, the Catholic Church fully supporting and backing Columbus's journey, the whole nine yards.
I got back a terse reply that this was the curriculum, so shut it.
Did I mention that I live in Canada?
