I am not an American, but I can't imagine that this will ever hold up.

In a world where filing cabinets and office safes are vanishing, the courts would be cutting off access to a major source of evidence they need for successful prosecutions. Financial crimes would become much harder to prosecute, and many "digital" crimes could become impossible.

I just cant imagine your government allowing that. The only alternative I can imagine is them making unbreakable encryption illegal for civilian use.
