It was almost 2 years ago, when the shooting at Virginia Tech occurred. There is some TV footage that stands out in my memory.
There were male and female law enforcement people on the scene. They were crouched behind trees and cars, while there were shots being fired from inside the building.
To be honest, I can not claim I would have have been brave or heroic under the same circumstances. Luckily, I have not faced such a situation.
But I expected better than that from law enforcement officers.
