The Fourth Amendment clearly states that law enforcement has to have a subpoena where a judge agrees there's a valid reason to demand private property, with very limited exceptions. E2E does not require a valid reason. Its only change as far as law enforcement is concerned is to stop monitoring when they do have a valid reason. (Which I think most people feel is as acceptable trade-off.)
