Tools and Resources for Bystander and Security Response

DHS's Active Shooter: How to Respond report provides a reference card on what on-site personnel should do in the event of a mass shooting attack (DHS, 2008a).

ALERRT maintains an educational portal called Avoid, Deny, Defend, which provides an overview training video and additional training resources, including a discussion on overcoming denial that an attack is happening and a discussion of what to do during law enforcement response (ALERRT, undated a).

Ready Houston provides a training video on Run, Hide, Fight (Ready Houston, 2012).
