Which procedure should be followed in the case of an active shooter event regarding mobile devices?

Silencing all mobile devices during an active shooter event is crucial for a few reasons. In such high-stress and threatening situations, loud noises can escalate panic and may inadvertently alert the shooter to a person's location. By keeping devices silent, individuals can help maintain a level of stealth that might be vital for their safety and the safety of others.

Furthermore, while communication is important, the priority during an active shooter scenario is often to ensure personal safety and to avoid drawing attention. Alerting authorities is indeed necessary, but this can typically be done without making noise or attracting unwanted attention, such as by using text messages or other discreet methods when safe to do so. In addition, devices can be utilized for communication later, once the immediate threat is mitigated.

Overall, the choice to silence mobile devices aligns with best practices intended to enhance safety and reduce risk during critical incidents.
