That's the point - make the code hard to get to so he's less likely to use it. It's just a thought exercise. There's so many things wrong with this 'solution' it would never work in practice. Most notably, no one would volunteer. Not because the President may kill them, but because they'd have to be at President's side 24/7. What if the volunteer is sick or injured and has to be hospitalized? No one can cover for him. The guy with the briefcase doesn't have that problem, he clocks out and the next guy carries the bag. It's an 'all your eggs in one basket' scenario.

So you did. My bad. Twitter has ruined my attention span.
