The last, I think, is the right answer. On the whole, when my laptop is stolen I don't want anybody to get *anything* useful off of that drive. If they can't get anything useful, then in particular they cannot get my crypto keys and I'm done. Law enforcement can get your crypto keys in some backward countries. Yup, the UK is one of them. I think we are more concerned with hacking and outright theft though, rather than being presented with a warrant and told "hand them thare key thingies over, sonny" Well I am anyhow :)
