Been there, done that for real- a coworker tried to bring a gun to work and kill us all he was stopped as he entered the building. I spent the week working with armed guards posted by the elevators, by the doors leading to every department, our poor receptionist had a guy siting with her at the front desk carrying three guns in case the ex coworker managed to get past the police in the parking lot, the security desk, elevators and the guy posted on the other side of the front door. It was quite the week...
