You can’t handle the truth. Son, we live in a world that has walls, and those walls have to be guarded by men with guns. Who’s gonna do it? You? You, Lieutenant Weinberg? I have a greater responsibility than you can possibly fathom.
— Jessep ‧ A Few Good Men

Our reading
An editorial interpretation.
The speaker defends a role of guarding, arguing that the world's protective walls need armed guards and challenging a lieutenant to take that duty. The tone is superior and confrontational, claiming a responsibility beyond the listener's grasp and dismissing the listener's ability to handle the truth.
