As for one going rogue, the founders never could imagine what all has brought it about..
They were, in fact, very concerned about the rise of a tyrant. Makes sense, given that they'd fought a revolution against the King of England, whom they regarded as just that.
And as for what was happening in major cities, they knew all about tensions in France. The Revolution started in 1789, after all; the Terror began a few years later. The cities AND the countryside of France were a mess. What followed that? A period of uncertainty, and then just what the founders feared: a new tyrant, in the form of Napoleon.
You really should do some reading.
