I'm just sitting here munching on my popcorn and don't have much to substantively add to this conversation except in response to the above. As I read it, what he meant is that if TSOs follow policy laid out by upper management it's not necessary for them to know every legal precedent, court ruling, etc.

For instance, as a LEO I need to know I can't shoot a fleeing felon in the back. I don't need to know that came about due to Tennessee v. Garner.

I now return you to your regularly scheduled bash fest.
