I haven’t searched yet, but I’m curious if this is the first time that someone’s being prosecuted for this. Authorities can detain a US Citizen and confiscate their electronic devices for forensic analysis, which should be a violations of the 5th, but the SCotUS feels differently.
If this is the first time a US Citizen has been prosecuted for refusing to unlock and handover their personal devices, then I’d wager that the authorities want to make this into a test case, and appeal it all the way to the SCotUS to rule that such a seizure and prosecution is not unconstitutional, or required for national security, or some other authoritarian bull.
