Hence the need to make sure you have the outer volume also set up with some innocuous stuff saved in there so you can 'if forced' give them something, suspicion doesn't constitute evidence and unless you hand it over they cannot prove otherwise. And yes I would take my chances with a "I'm sorry I just cannot remember the password" over handing them my ass on a plate any day, the burden of proof resides with them to prove remember, innocent until proven otherwise. Never talk to the police.
