Technology can strengthen law enforcement, but it cannot replace trust
Across the world, governments are equipping their police forces with digital tools that promise speed, coordination, and foresight — yet the law, as one South African legal scholar warns, has not kept pace with the power these systems confer. Advocate Justice Khoza of North-West University reminds us that in a constitutional democracy, the capacity to act and the right to act are not the same thing. Ethiopia's deployment of digital policing infrastructure and South Africa's own contemplation of smart stations bring into focus a question as old as governance itself: who watches the watchers, and by what rules?
- Governments are racing to digitize law enforcement, deploying surveillance platforms and automated data systems faster than legal frameworks can absorb them.
- The danger is not the technology itself but the constitutional vacuum it can create — where vast personal data is collected, stored, and analyzed with little public accountability.
- South Africa's Bill of Rights, privacy protections, and the Protection of Personal Information Act exist precisely to constrain state power, yet digital policing risks quietly eroding those boundaries.
- Legal experts are calling for a high bar: any smart policing system must be transparent, equitable across communities, and subject to legal challenge by ordinary citizens.
- The stakes are sharpening — nations must now decide whether digital tools will serve the law or gradually rewrite what the law permits.
Governments around the world are moving quickly to digitize their police forces, deploying smart stations, integrated data platforms, and surveillance tools that promise faster crime detection and better coordination. Ethiopia has already taken steps in this direction. But as these systems multiply, Advocate Justice Khoza, a law lecturer at North-West University's Faculty of Law, is sounding a warning: innovation in policing is outrunning the constitutional safeguards meant to govern it.
Khoza does not oppose digital tools outright. He acknowledges they can genuinely improve a police force's ability to track cases, identify crime patterns, and deploy resources more effectively. The problem, he argues, is that technological power must remain tethered to legal limits — and right now, that tether is fraying. In South Africa, the Constitution's right to privacy, the requirement that government action be lawful and fair, and the Protection of Personal Information Act all set boundaries that digital policing systems must respect.
The tension runs deep. Digital systems create permanent records, enable predictive analysis, and collect data at a scale that paper-based policing never could. Efficiency gains are real — but so are the risks to privacy, fairness, and citizens' ability to know and contest what the state holds about them. Khoza insists that any adoption of smart policing must clear a high bar: systems cannot undermine constitutional rights, cannot create unequal policing across communities, and cannot operate beyond public scrutiny.
His deeper argument is that technology cannot substitute for the hard work of building legitimate institutions. A data platform cannot manufacture accountability if no one is responsible for how data is used. Surveillance tools cannot generate the public trust that comes from police who are genuinely answerable to the communities they serve. As more countries embrace digital policing, the defining question is whether these systems will be made to serve the law — or allowed to quietly reshape what the law permits.
Governments around the world are racing to digitize their police forces. Smart stations with integrated data platforms, automated reporting systems, and surveillance tools promise faster crime detection, better coordination between units, and quicker response times to security threats. Ethiopia has already moved in this direction, deploying digital infrastructure designed to streamline how law enforcement operates. But as these systems spread, a legal scholar at North-West University is raising an alarm: technology is outpacing the law.
Advocate Justice Khoza, who teaches law at NWU's Faculty of Law, argues that the expansion of digital policing is creating a gap between what governments can do and what they should be allowed to do. The systems themselves are not the problem, he says. Digital tools can genuinely strengthen a police force's capacity to track cases, identify crime patterns, and mobilize resources faster than traditional methods. The problem is that innovation in policing has a way of moving ahead of constitutional safeguards.
In a constitutional democracy, Khoza insists, technological power must remain tethered to legal limits. South Africa's own Constitution provides those limits through the right to privacy and the requirement that government action be lawful and fair. The Protection of Personal Information Act adds another layer, governing how personal data can be collected and processed. When police deploy digital systems to gather and store information about citizens, those systems must operate within these boundaries. "Technological innovation in policing can strengthen state capacity," Khoza said, "but in a constitutional democracy it must remain firmly anchored in the Bill of Rights, legal accountability and public trust."
The tension is real. Digital systems collect vast amounts of data. They create permanent records. They enable pattern-matching and predictive analysis that would be impossible on paper. All of this can make policing more efficient. But efficiency is not the only value that matters. Privacy matters. Fairness matters. The ability of ordinary people to know what information the state holds about them, and to challenge it if it is wrong, matters.
Khoza acknowledges that South Africa could adopt elements of smart policing. But any adoption would need to clear a high bar. New systems cannot undermine constitutional rights. They cannot create a two-tier system where some communities get better policing because they are more digitized, while others fall behind. They cannot operate in the shadows, beyond public scrutiny or legal challenge. And they cannot replace the human foundations of good policing: professional training, institutional accountability, and genuine public trust.
The deeper point Khoza is making is that technology is not a substitute for the hard work of building legitimate law enforcement. A smart police station cannot fix corruption. A data platform cannot create accountability if no one is held responsible for how the data is used. Surveillance tools cannot replace the trust that comes from police who are answerable to the communities they serve. "Technology can strengthen law enforcement capacity," Khoza said, "but it cannot replace the foundations of effective policing, strong institutions, professional accountability and public trust."
As more countries adopt digital policing, the question becomes urgent: Will governments treat these systems as tools that must serve the law, or as tools that can reshape what the law allows? The answer will determine whether digital policing makes democracies safer or simply gives them new ways to infringe on the rights of their citizens.

The Hearth Conversation Another angle on the story
Why does it matter that Ethiopia has already deployed these systems? Isn't that just one country experimenting?
Because it shows the technology works—at least operationally. Once you prove something works, other governments want it. And once it spreads, the legal questions become harder to answer retroactively. It's easier to build safeguards in from the start than to dismantle a system that's already embedded.
But Khoza seems to be saying the law already exists in South Africa. So what's the problem?
The law exists on paper. The problem is enforcement. When a police force has a new digital tool, they want to use it. And the temptation to use it in ways that bend or break the rules—collecting more data than necessary, sharing it without proper oversight, using it to target certain communities—that temptation is enormous. Laws only work if someone is actually watching.
He mentions that technology cannot replace trust. That sounds almost nostalgic. Can't a well-designed system actually build trust?
A system can make policing more efficient, sure. But trust is not about efficiency. Trust is about knowing that someone is accountable if they abuse their power. A digital system that collects data on millions of people but has no real oversight mechanism doesn't build trust—it just makes abuse harder to detect.
So what would a legitimate digital policing system look like?
One where the data collected is limited to what's actually necessary. Where citizens can know what information is held about them. Where there are real consequences if police misuse the system. Where the technology is transparent enough that courts and civil society can audit it. And where it's designed so that it doesn't create inequality—so that poor communities don't get worse policing just because they're harder to digitize.
Is Khoza optimistic that South Africa could actually build something like that?
He's not pessimistic, but he's realistic. He's saying it's possible, but only if the government treats the Constitution as a real constraint, not a box to check. That's harder than it sounds.
