help me write it in a simpler way: In conclusion, the importance of a well-coordinated and effective response to an active shooter situation cannot be overstated. The roles and responsibilities of each agency involved, from the El Paso Police Department to Homeland Security, are distinct yet interconnected, necessitating clear and consistent interagency communication. The National Incident Management System (NIMS) and the Incident Command System (ICS) provide the necessary framework for this communication and coordination. Moreover, comprehensive training, including FEMA's specialized courses, is crucial in equipping these agencies with the skills and knowledge they need to respond effectively. This training should encompass a range of areas, from tactical response to active shooter situations, to interagency communication, to public information dissemination. Ultimately, the goal is to ensure that all agencies can work together seamlessly in the face of an emergency, protecting the public and neutralizing the threat as quickly and efficiently as possible. This requires not only robust planning and coordination but also a commitment to ongoing training and learning, to continually improve and adapt our emergency response capabilities
