Major, I'm glad you didn't have to shoot this girl. But um…if she had been a suicide bomber, then your agency's protocol would have just resulted in a lot of severed limbs, shrapnel wounds, flail chests, burning cars, shattered glass, and other really colorful "art."
To be fair, your officers did a good job of stopping her outside of the terminal.
But their actions afterward show how ill prepared we are as a nation to counter the waves of suicide bombers that are sure to be detonating soon at movie theaters, restaurants, grocery stores, and shopping malls near you.
Your protocol begs the question, What would your officers have done if she had made a move? You say they "might" have used deadly force. I hope you really mean that they would have.
And BTW, if she had been a real suicide bomber, commands of "Don't move!" won't work. By the time an officer says "don't," he and everyone nearby will be dead or dying.
