The problem with school education is that it isn't aware of the moral context in which it operates. Herding children into classrooms and telling them what to learn is a horrible thing to do.
And, under threat of punishment, once can't learn efficiently, anyhow.
Yes, and not only the moral context. A school's job is to help turn little animals into citizens by introducing them to the broader world. How does shoving them in a box for 8 hours a day where they have to sit in one place make any sense if that's your goal.
A more secure society wouldn't have secret agencies operating in peacetime. Why? Because their mandates, budgets, policies are also secret and subject to mission creep.
Except that this specific document comes with good advice and rationale. There is nothing here that indicates a secret agenda. It's not as if the document is telling you to install a backdoor for them.
And, under threat of punishment, once can't learn efficiently, anyhow.
