Are you familiar with parallel construction? That's what this is for. If they have a warrant and show it to you, it says what they can search and why. If they don't tell you what they're searching for and why, they can look for anything, and then construct a separate scenario which just happens to expose the thing they knew would be there from the first fishing expedition. They then use this (usually circumstantial) evidence to accuse you of a crime, and they can win, even if you didn't commit a crime, but it looks like you did. And now they can do it with digital information, automatically, behind the scenes, without your knowledge. (or they can take your laptop and phone and do it then)
