What are you trying to prove? He never said you're wrong, just the fact that something is illegal doesn't mean that it won't happen to you, just that it's illegal - those are just words written in a book somewhere. Even so-called law bound adversaries break the law all the time. A cop beating you senseless or breaking into your home is illegal, but it happens all the time. You're welcome to sue after the fact.
This is not relevant to memory encryption, after all the police could just plant any false evidence. You use video camera/CCTV and other evidence gathering to document such illegal police action.
Suing after the fact is a valid strategy and in free countries this would allow you to exclude illegally obtained evidence or evidence lacking proper chain of custody.
