James R. Taylor patented a desk whose top doubles as a bullet-resistant shield as a response to school shootings in the 1990s.

Another object is to provide a shield that is configured to function normally in an innocuous mode as an ordinary desk work surface but that can be easily and quickly removed from the desk for use as a personal shield against projectiles including but not limited to bullets, knives, shrapnel, or flying debris that might be encountered in naturally occurring events such as earthquakes, fires, or storms.

I doubt that Mr. Taylor's desktop shield is in use in many educational institutions. I suspect most parents would be  scared off a school that had to resort to such an extreme defensive tactic.
