Accra: The recent surge in violent incidents within public spaces, particularly in schools and hospitals, has exposed critical gaps in Ghana's security systems and reignited calls for a more comprehensive Public Place Security (PPS) framework. Notable incidents such as the fatal shooting at Nalerigu Senior High School in the North East Region and the alleged assaults at the Greater Accra Regional Hospital in Accra underscore the urgent need for a security overhaul that protects the most vulnerable spaces in society.
According to Ghana News Agency, Lieutenant Col. Martin Dziedzorm Dey, a Security Architect and Columnist, emphasized that the cornerstone of any effective security system must be grounded in the principles of deterrence, delay, denial, detection, and devalue. 'These principles are not isolated actions, but parts of a layered framework designed to prevent, slow, and neutralize threats. Deterrence discourages hostile actions, delay and denial make it difficult for an assailant to achieve their objective, detection ensures swift identification of breaches, and devalue minimizes potential impact,' he explained.
He noted that an integrated security architecture must combine technology, physical infrastructure, and skilled human resources, each reinforcing the other to form a resilient defense. 'One critical tool in this layered approach is the Access Control System (ACS), which regulates and restricts entry into sensitive areas,' he stated. From biometric scanners and smart key cards to advanced integrated systems, ACS embodies denial and delay, ensuring that only authorized persons could access designated zones, he said, adding that when deployed strategically at schools and hospitals, it could serve as a frontline barrier against malicious intrusion.
Complementing access control, surveillance systems remain indispensable. However, Lt Col Dey noted that many facilities rely on outdated CCTV setups with blind spots and inadequate coverage. Modern surveillance, he said, must incorporate Artificial Intelligence (AI)-enabled cameras capable of voice recognition and behavioral analysis. Such systems could detect suspicious patterns and flag threats before they materialize, offering invaluable early-warning capabilities.
Equally important is the human element of security. While technology provides efficiency, personnel remain the first responders. 'Deploying a guard from a bank to a hospital or school without specialized training for that environment compromises the integrity of PPS,' Lt Col Dey cautioned. He stressed the need for environment-specific training, high situational awareness, and proactive intelligence gathering to complement technological tools.
Lt Col Dey argued that the country must move away from fragmented and reactive security practices towards a unified, multi-layered model tailored to the realities of public spaces. By aligning advanced technological solutions with specialized personnel training and strictly applying the five principles of deterrence, delay, denial, detection, and devalue, Lt. Col. Dey said he believes schools, hospitals, and other public institutions could be transformed into safer environments for all people.
