Guy locked-up forever for forgetting his password.

[Aoi Magi]

Yes someone can easily set someone up like this, but what I want to know is should the feds really need to depend on the suspect to reveal the password, or can they, due to circumstantial evidence, legally crack open and check the data themselves? Cause it is pointless to hold him indefinitely and is definitely a violation of his rights... so either they have to let him go, or find some way of checking the evidence without his cooperation. If they can't do the later, then why bother holding on to him?
