The problem with FDE, is that the judge/jury are seriously unlikely to believe you've "lost" your passphrase if they have evidence you've been logging in periodically and there is a record of this.Every tool has a place, and also limitations. Things like FDE should be treated for what they are, a last resort. Like the forensic scientist doing a AMA over in the other thread is saying, the best thing is to have a small footprint in the first place.
