In an active shooter situation, which of the following is the LEAST safe location to consider barricading?

In an active shooter situation, considering safety is paramount, and the least safe option among the choices provided is to barricade under the desk behind the cubicle wall. This option offers minimal protection and concealment. The lack of a solid structure overhead or around the individual limits the ability to shield oneself from bullets or other dangers. Moreover, being under a desk provides very restricted movement and visibility, making it difficult to react to the situation if it changes dramatically.

In contrast, barricading behind a locked door, in a secured area, or even in a room with no exit typically involves more substantial barriers that can deter or delay an active shooter. These environments provide better concealment and security, allowing individuals better opportunities to respond to the scenario effectively, whether that be by escaping, barricading, or communicating for help.
