@sickburnbro The utility of "secrets" decreases with time. Having a mole inside constantly feeding you updated intel is very valuable, but someone who got fired half-remembering things from a while ago is not really as actionable for the enemy.

There isn't that much information they could leak that would be truly dangerous.
What secrets are long-term useful? Things like military tech only apply to a small minority of government workers in defense (hasn't even been touched yet) and they'd have to actually designs for that to be meaningful.

The identity of foreign spies? Those are their friends within the agency they'd be betraying. And if they do, good riddance. Spooks are not our friends.
