I'd warn him to beware of "What if..." worlds. In such places, anything is possible. Fearing the possible makes one paranoid and untrusting.
What if he is the terrorist and wants to more readily spy on the American people? Or a similar, more likely scenario, of what if the government has a spy from another country? Do we want them to have all of our information in their hands? If encryption is weakened they can more easily spy on our political leaders.
What about national security? Lowering encryption standards hurts national security. As an American patriot why would you want to hurt national security? For a bit of promised security? The current mass surveillance has prevented 0 attacks. Who is to say more surveillance would prevent any attacks? You can say for certain it would hurt national security (bad guys can use backdoors too) - but you cannot say for certain it would prevent any attacks. So it's a "lose/maybe-win" scenario. Not one in the countries best interests, if you ask me.
