Just Skip to Step 7, Eh?

The Department of Homeland Security has helpful advice about reacting to a shooter in the workplace. Sadly, it doesn't include anything about shooting back if you are armed. Lots of running and hiding advice (but do it quietly so as not to disturb the first responders if they happen to be running an exercise on site and so get there quickly).

Oh, and heave stuff at the attacker, or otherwise magically "incapacitate" them. Yeah, a firearm might accomplish that. If you didn't obey the "weapons free zone" that the shooter clearly doesn't care about. Oh well, that high-capacity stapler will work just swell.

Absent a firearm, why not just go right to the heart of the advice?

Wow, that is old. Cigarettes and neckties in a bar?
