What should you do when confronted with a gun-wielding madman?
To disarm a gunman, you'll need to take his focus off his weapon and his plan of attack. To do this, you might throw chairs, laptops, or fire extinguishers at him, or set off the sprinkler system or fire alarm. Then, you'd want to pick up a desk or some other shield and charge right at the killer. There's a chance you'll be killed in the process, but if two or three people rush at once, there's also a chance that somebody will take him down. (Unarmed civilians who band together have a much better chance of surviving an attack.)
