FWIW, I've had a warrant executed against me by the FBI. They seized every electronic device I own, and forcibly took my biometric data(fingerprints, face scan, retinal scan) in the hopes they could unlock my devices with it. They were unable to access any LUKS-encrypted volumes, and were less than happy about that situation. Can't say much else unless I'm good with 99x anxiety for the next few days.
ps: not charged, not convicted, very innocent. not a fan of the justice dept.
