I read a pretty compelling argument by a lawyer that we're looking at this the wrong way. (I Am Not A Lawyer)
Their point was that if the law is knocking on your door to legally search your house, and you have records of your criminal empire printed out in boxes in your attic, or just non-illegal things you don't want people to see, and you burn those papers while the law waits out front, you're guilty of destroying evidence. The fact that this is all digital changes nothing.
The problem is with the legality of the search, not the charge of destroying evidence.
