Oh that’s so simple and clever!

So the cops keep all phones plugged in and unlocked at all times to prevent them from re-locking?

If they can't keep them unlocked, they at least don't want them to reboot, since that puts the phone in a less exploitable state.

If they never reboot, then the phone can just be kept powered and isolated for years if need be to find an exploit in the AFU (after first-unlock) decrypted but screenlocked state.
