LEOs like firefighters, the military, etc, are an elite group of people who agree to put themselves in harm's way, every day. They agree that when there is an armed perp on the loose, they will not barricade themselves in their homes, but will leave positions of safety and go hunt the perp, so he doesn't kill us.
When there are supplies to be delivered to a remote outpost, and IEDs on the road, they still drive that dangerous route, unquestioningly
They agree that when a building is burning, then will not run away, like any “smart’ person would, but will, every time, run into that building to try to save us, and on 9/11, most of them stayed there forever.
And when there are incidents like that, from a simple auto accident to a huge plane crash, or 9/11, who stays around and picks up the bodies... and body parts... They do.
Are they a special class of people? You betcha!
Good answer. Anyone who would shoot a cop is a special class of person too, so dangerous that a manhunt ensues to get him off the street RIGHT NOW.
Looks like the perp shot himself...unsuccessfully.
