The sad answer – even after dozens of school shootings and even in the wrenching aftermath of the latest one – is that we don’t know. There is a gaping lack of knowledge and research when it comes to measuring the effectiveness of preventative measures as they relate to school shootings.
Early detection of weapons – and their users – in the school environment can minimise the impact of school violence. For example, ZeroEyes is an intelligent video analytics platform, powered by artificial intelligence (AI), to detect weapons and recognise faces in real time. The company’s goal is to provide school administrators and decision-makers with a simple, intuitive situational awareness platform that gives first responders a tactical advantage.

× An emerging tool in campus security is audio analytics: Aggression and gunshot detection are some of the best security tools in the campus security market when it comes to detection, intervention and deterrence. Aggression detectors are capable of accurately recognising duress in a person’s voice.
The software automatically and objectively detects the presence of rising human aggression, anger or fear, and subsequently warns staff by a visual alert or alarm trigger. A gunshot detector recognises firearm discharge from various firearms in different settings. Within seconds of a gunshot, the software accurately classifies and triggers an immediate notification.
Emergency response technology
CLASS [Crisis Lockdown Alert Status System] by Sielox is an incident and crisis management solution
Emergency response in also important, and technology can play a role. For example, physical security company Sielox has adapted the idea of using a colour scheme to characterise an emergency situation into its electronic security system. CLASS [Crisis Lockdown Alert Status System] by Sielox is an incident and crisis management solution that uses a variety of colours to designate the emergency conditions in various parts of a school building – red to alert to a crisis condition and green to designate "safe/secure".
Colours are displayed on a schematic of the building, and new colours have been added, too, such as yellow for “unaccounted individual", orange for “disturbance” and blue to designate a medical emergency. CLASS offers five different alert levels and eight different colours that are configurable to denote a wide variety of emergency or non-emergency situations (such as maintenance or homeroom check-in status).

Non-lethal methods to suppress active shooters in schools are also emerging. For example, one remotely deployed threat suppression system drenches a perpetrator with a repulsive water-based solution, thus impairing their ability to enact violence. The solution irritates eyes, throat, lungs and skin, but does not cause permanent injury. Cleanup is easy using water and detergent. The solution is manually deployed in predetermined zones, which limits the affected areas in a building. Touch-screen control enables rapid deployment, which can also be integrated with Threat Alert buttons and/or gunshot detection.
ShotSpotter gunfire tracking
Gun violence is also an issue in the neighborhoods where schools are located
Beyond the schools themselves, gun violence is an issue in the neighborhoods where schools are located. ShotSpotter, Inc. released data tracking gunfire in and around public K-12 school communities within ShotSpotter coverage areas during 2017. The data revealed more than 4,800 gunfire incidents occurred during school hours within a one-half mile radius of public K-12 schools and within the coverage area.
There are 2,320 public K-12 schools and over 1,079,700 students within ShotSpotter coverage areas in 77 cities in the United States. The ShotSpotter study tracked and analysed data on the number of gunfire incidents that occurred at or near those schools across the time period from 7 a.m. – 5 p.m. local time, Monday – Friday, including summer and holidays.
On a positive note, awareness of high-profile school violence has prompted action. Schools and universities are most certainly safer than ever before. High-profile incidents, especially active shooters tragedies, have increased collective security awareness. Heightened awareness leads to safer practices, improved emergency preparedness and security technology innovations.
Collaborative efforts that involve stakeholder groups, such as administrators, responders and students, are the key to a safer learning environment. Investing in technology advances in 1) access control (e.g. electronic access, visitor management) and 2) communications (e.g. duress capabilities, mass notification) is the most effective way to protect people.
