What is the preferred method for ensuring safety during initial entry in an active shooter response?

The preferred method for ensuring safety during initial entry in an active shooter response is threshold evaluation. This involves assessing the situation before entering a potentially dangerous environment. By conducting a threshold evaluation, officers can gather critical information about the layout of the area, the location of the shooter, potential victims, and any immediate dangers. This assessment allows responders to make informed decisions and strategize their actions to minimize risks to themselves and others.

During this evaluation, officers typically look for things such as signs of the shooter's location, the presence of hostages, escape routes, and potential cover. This careful approach is essential in ensuring a coordinated and effective response while maintaining the highest possible level of safety for both the responders and any potential victims.

While unit dispersion, heavy weaponry, and clear observation are also important elements of an active shooter response, they do not provide the same level of immediate situational awareness that threshold evaluation offers at the moment of entry. This makes threshold evaluation a critical step in the response process to effectively address the threats posed in such high-stakes situations.
