Full disk encryption isn't an "I'm so clever" excuse - take Ulbricht for instance even if he had shut down his computer before being arrested FDE wouldn't be help from someone asking his password. If you've been seen using the computer recently it's going to pretty hard to convince the courts that you don't know the FDE encryption password. "I'm so clever" is running something that destroys all the data on your laptop and then claiming that you didn't do that in response to an investigation (and therefore obstructed justice). Even with Truecrypt installed there's still plenty of ways evidence can be collected that can be used to demonstrate that you realistically have access to encrypted and hidden data. It isn't as simple as installing Truecrypt and thinking you're safe. Be it recently accessed documents lists for folders that don't exist, Truecrypt being installed, having software installed (and with recent execution dates) that don't have any corresponding data files anywhere on the system etc etc. Think of it like Cold War espionage - you could live your life by "Moscow Rules" where you do everything possible to be able to claim, convincingly, that you're not being so clever. However even very talented agents and intelligence assets failed to not slip up on many occasions, and it involved huge amounts of time, effort and money on their parts.
