Does patrolling with 0 unrest kill population too?

The question in this thread was whether patrolling reduces unrest if there is no unrest present. It doesn't, and because of this you have no reason not to patrol with your armies when they are in your fortress: if there is a surprise attack, your forces will catch the attackers.

Just so there is no misunderstanding, the question was whether patrolling reduces *population* if there is no unrest present (*not*: "reduces unrest").
Oh, and there are still plenty of reasons not to patrol with your armies...
