I think the sane thing to do is assume they are going to ask for legislation to force large companies that do online communication (facebook, whatsapp, twitter, apple, etc) to keep their system potentially and practically back door capable. That is something that would be possible to implement. It is also something with a historical precedent (look into how they responded to the BBM situation after the London riots). If we don't want that to happen then the smart thing to do would be act as if that is what they are proposing. If they propose something even worse it isn't like it will have been wasted effort.
