Navigating the Growing Threat of Active Shooter Incidents:
A Call for Preparedness

Author: John Carney, District Manager, Doyle Security Services


As a former Bureau of Special Operations Sergeant with the Nassau County Police Department (NCPD), I was directly involved in training and equipping our personnel for the potential response to active shooter incidents for over 14 years. After retiring from law enforcement, I had an opportunity to utilize that experience to develop and deliver active shooter awareness training to civilian employees at Brookhaven National Laboratory. In my current role as District Manager at Doyle Security Services, that passion to educate and prepare my clients and colleagues for such catastrophic events remains as strong as ever.

Understanding Active Shooter Incidents

The FBI defines an active shooter as one or more individuals actively engaged in killing or attempting to kill people in a populated area by use of a firearm. The active and ongoing nature of this extreme
violence required a significant change to traditional law enforcement responses to these incidents,
leading to the rapid deployment tactics utilized following the Columbine High School tragedy in 1999. Since that precipitating event covered extensively by the media over 20 years ago, this national (and international) dilemma has generally increased in both rate of occurrence and in the number of annual casualties. In 2022, active shooter incidents occurred in 25 states and the District of Columbia across seven location categories: open spaces, commerce, residences, education, government, houses of worship, and health care facilities.

In 2022, the FBI designated 50 shootings as active shooter incidents. Though this number represents an 18% decrease from 2021, it is still a staggering 66.7% increase compared to 2018. With such a rapid escalation, it is crucial for organizations and individuals to be as prepared as possible for the unfortunate reality of these situations.

The 50 active shooter incidents in 2022 killed 100 people and wounded 213 others. In a recently issued report, “Active Shooter Incidents in the United States in 2022,” the FBI and other agencies noted that “46% of the incidents occurred in open spaces (23), followed by 28% in commerce (14), 8% in education and residences (4), 4% in houses of worship and government (2), and 2% in health care (1).” You can read the entire FBI report by clicking here.

In 2023, there were numerous active shooter incidents that shook communities across the United States. Some of these include:

  • May 15: Farmington, New Mexico: 4 people were killed and 6 injured by gunfire, including 2

The Impact on Communities and Organizations

Despite the overall low probability of active shooter incidents, these are high-impact events which have far-reaching consequences for communities and organizations, beyond the immediate loss of life and physical injuries. Survivors, families, and communities can experience long-lasting emotional and psychological trauma, while businesses can suffer damage to their reputation, financial losses, and potential legal liability.

The Need for Preparedness

Given the unpredictability and tragic consequences of active shooter situations, it is essential for organizations to invest in preparedness. This includes:

  • Conducting threat assessments: Identify vulnerabilities and potential threats within your organization; establish and train threat assessment teams to evaluate personnel concerns.
  • Developing Emergency Action Plans: Create a comprehensive plan for responding to active shooter incidents and other emergencies. Elements should include mass communication / alarm systems, immediate lockout capabilities, evacuation and lockdown procedures, identification of proximate assembly areas, and designation of internal shelter-in-place areas and “safe rooms”.
  • Providing training: Offer active shooter training for employees, emphasizing the importance of situational awareness, communication, and response options such as "Run, Hide, Fight."
  • Implementing enhanced security protocols: Strengthen existing security measures, including access control, surveillance, and increased security personnel.
  • Encouraging information sharing and collaboration: Foster a culture of reporting concerning or suspicious behavior with supervisors, human resource representatives, and when appropriate, local law enforcement. Potential red flags should never be ignored .

Role of Law Enforcement and First Responders

During an active shooter incident, law enforcement and first responders play a critical role in neutralizing the threat and providing aid to the victims. Effective collaboration and communication between organizations and law enforcement can help mitigate the impact of these incidents.
Establishing relationships with local law enforcement agencies and conducting joint training exercises can further enhance preparedness and response capabilities.
