ViVA IMPIMPI.
What a suburban WhatsApp group taught me about impimpi, collective efficacy, and being the Black man they were watching.

There is a WhatsApp group for the suburban street I live on. It announces all sorts of activity, a car idling too long, a gate left open, a stranger on foot. Often the stranger on foot is me. A Black man walking his own street, flagged by camera and by habit, mostly by residents on the far side of sixty. There is prejudice in that group. There is also, alongside the prejudice, a level of street-level civic activism I have come to admire, and I want to hold both of those truths at once, because pretending one cancels the other would be dishonest.
Two Incidents.
A car parked next to a neighbour’s yard, close to the City Power meter boxes. Facial-recognition cameras and motion sensors picked it up immediately. The group lit up: “Car with two Black men, at the meter boxes.” Three white women went straight over, asked for identification, and phoned the employer to verify the technicians’ ID and employee numbers. Everything checked out, and the two men were left to finish their work undisturbed. In a similar incident on another street, the car sped off the moment the same kind of women showed up asking questions, which tells you the checking itself was doing something.
A smaller story, same instinct: my puppy slipped out of the yard unannounced. A neighbour three or four houses down found him, took a photograph, and posted it to the group, “beautiful puppy found, don’t worry, he’s at my place playing with my dogs, and he’s been fed and watered.” No drama, no interrogation. Just a street that had decided, collectively, that a stray puppy and an unfamiliar car at a meter box were both the group’s business.
It became clearer to me that we need more impimpi, more snitches, more nosey neighbours, to have a thriving democracy.
From Bheka Indaba Zakho to Co-Policing.
Township life and the apartheid years taught us the opposite lesson: bheka indaba zakho, mind your own business and never be impimpi, never be the one who snitches. That instruction made sense in its context. Snitching under apartheid meant collaborating with an illegitimate, violent state to suppress freedom; staying silent was often the only ethical option available. But we live in a different context now, rainbow, constitutional, democratic and the instruction has not caught up with the change.
The best role models I’ve found for this newer version of citizenship are white women, followed by older white men. They are the self-elected police, minus the violence. The first to complain about a power outage, a missed rubbish collection, potholes, a dry tap. They do not mind only their own business, they mind the whole street’s business, on principle.
What the Literature Actually Says
I went looking for evidence on whether this kind of minding-everyone’s-business actually strengthens a democracy, or whether it is just busybody suburbanism dressed up as virtue. The evidence is stronger than I expected, and it clusters around four findings.
Four Empirical Pillars
Collective Efficacy — Robert Sampson’s landmark 1997 study in Science defines collective efficacy as mutual trust among neighbours combined with a shared willingness to intervene for the common good. Neighbourhoods with high collective efficacy have measurably lower rates of both property and violent crime, independent of income level. Watching each other is not incidental to safety, it is a primary mechanism of it.
Countering the Bystander Effect — political science treats mature democracies as needing citizens who see themselves as co-producers of public goods, not passive consumers of government services. The classic bystander effect says the more people witness a problem, the less likely any one of them acts. Localised WhatsApp groups break that pattern by converting an abstract civic duty into one specific, immediate task, report the leak, track the missed collection, rescue the puppy.
Impimpi Reclaimed — under a constitutional democracy the relationship between citizen, community, and authority is structurally different from what it was under apartheid. Community Policing Forums formalise exactly this shift: citizens are no longer informing on each other to an oppressive state, they are actively protecting their own constitutionally guaranteed rights to safety, infrastructure, and dignity.
The Critical Caveat — the same literature that validates the effectiveness of these watch groups is equally clear about their dark side. Suburban WhatsApp groups frequently conflate safety with racial and class homogeneity. A Black technician doing his job, or a Black resident on a walk, gets coded as a threat by historical reflexes that have nothing to do with what he is actually doing.
That fourth pillar is the one I live inside every time I walk my own street. The same system that found my puppy in twenty minutes is the system that flags me for existing on it. Both things are true, and the second does not disprove the first, it just means the tool is unfinished, aimed imprecisely, still running on reflexes built for a different country.
Weighing the Trade-off
The comparative picture, once you lay the different forms of civic intervention side by side, is one of real benefit sitting next to a real and specific risk, not a case for abandoning the model, but a case for correcting its aim.
ACTIVE INTERVENTION
Engagement Type: Active Intervention (checking IDs, asking questions)
Democratic Benefit: Immediate deterrence of structural theft and utility tampering.
Primary Risk: Escalation, vigilantism, or confrontation if uncoordinated with law enforcement.
MUNICIPAL ACTIVISM
Engagement Type: Municipal Activism (reporting blackouts, tracking rubbish collection)
Democratic Benefit: Forces municipal accountability and maintains property values.
Primary Risk: Reinforces privilege when resources are skewed toward affluent, vocal neighbourhoods.
DIGITAL WATCH
Engagement Type: Digital Watch Networks (WhatsApp alerts, facial-sensor cameras)
Democratic Benefit: Hyper-fast response times and high collective situational awareness.
Primary Benefit: Systemic bias, racial profiling, and paranoia targeting innocent citizens on demographic markers.
Holding Both Things
I am not going to pretend the profiling doesn’t sting, because it does, every time. But I am also not going to pretend the alternative, a street where nobody notices anything, where a car at a meter box gets no scrutiny at all, where a lost puppy just stays lost, is the safer or more democratic option. The fix I want is not less noticing. It’s noticing that is accurate. A neighbourhood that checks identification with the same rigour whether the technician is Black or White is a neighbourhood doing collective efficacy correctly. A neighbourhood that only reaches for the phone when the technician is Black is doing something else, and calling it safety.
Our country needs more citizens like those white women and it needs those same citizens to point that same instinct at every car, not just the ones driven by Black men.
Democracy does not run on the goodwill of officials alone. It runs on ordinary residents deciding, street by street, that the meter box, the rubbish bin, the power line, and the missing dog are all their business too, that being a citizen is a verb, not a status you hold quietly at home. Impimpi, in this newer sense, is not betrayal. It is the refusal to let the bystander effect win. I want more of it on my street. I just want it aimed at the car, not at the colour of the hands on the meter box. I want more of it, at the Madlanga Commission, let the guilty at the Madlanga Commission drink gallons of water on their long walk to the gallows.
