Vigilantism is action by private individuals who take on the functions of investigation, judgment and punishment outside the police, the courts and the law. It is the concept that best explains a whole family of characters in this archive —it appears in 27 case files— and the one most often confused with its legal neighbour, which is an entirely different thing.
Self-defence
Self-defence is a justification recognised by criminal law: it answers an attack that is under way or imminent, it is necessary to repel it, and it is proportionate to it. It is lawful precisely because the state cannot arrive in time, and it ends the instant the attack stops. Vigilantism begins exactly where self-defence ends: it acts on harm already done, and what it claims is not protection but punishment —to investigate, sentence and execute— functions the state monopolises. The line is temporal and functional, not a matter of intensity: it does not depend on how much violence is used, but on whether the act is happening or has already happened, and on whether the aim is to stop it or to settle the score. There is a third figure in between worth keeping in view: citizen's arrest, which many legal systems permit, authorising someone to detain a person in order to hand them to the authorities — never to judge them.
// In the archiveLegitimacy, not malice
What criminology observes consistently is that vigilantism does not correlate with the malice of those who practise it, but with the perceived weakness of the institution. It appears where the police do not arrive, where they arrive and do nothing, or where people have stopped believing they will: lynchings in areas with no state presence, neighbourhood patrols where reporting a crime produces no response, armed groups filling a vacuum. That is why it is so uncomfortable to judge and so easy to applaud. And it is why the fictional vigilante works: the script first manufactures the institutional vacuum —the corrupt cop, the bought judge, the system that lets the guilty go— and only then introduces the person who fills it. What persuades us on screen is what persuades people in reality.

// The crackThe problem is not the first bullet
The objection to vigilantism is not sentimental. It is that it lacks the three things that make punishment bearable: evidence, proportion and review. There is no defence, no standard of proof, no appeal, and error is irreversible because nobody above can correct it. On top of that it rarely stops where it promised: the literature on self-defence groups regularly documents the drift from protecting a neighbourhood to controlling it, ending in charging for the protection they once gave free. Understanding why it appears —a state that fails to deliver— is indispensable for preventing it, and legitimises it not one gram: to explain is not to excuse. The answer to an institutional vacuum is to fill it with institutions, not with armed private citizens.
Three key ideas
- Vigilantism is taking on investigation, judgment and punishment outside the state. Self-defence answers an attack under way and ends when it stops; vigilantism acts on harm already done and seeks to punish, not to protect.
- It correlates not with the malice of its practitioners but with the perceived weakness of institutions: it appears where police do not arrive, do not act, or are no longer believed. The fictional vigilante uses the same mechanism —manufacture the vacuum first, fill it second.
- It lacks the three things that make punishment bearable —evidence, proportion and review— and its errors are irreversible. The literature also documents the usual drift: from protecting a neighbourhood to controlling it and charging it.

Theory questionsFrequently asked questions
What is vigilantism?
Action by private individuals who take on the functions of investigation, judgment and punishment outside the police, the courts and the law. It is not protecting yourself from an attack under way, but settling a score for harm already done by occupying the state's place.
What is the difference between vigilantism and self-defence?
Self-defence is lawful: it answers an attack under way or imminent, is necessary to repel it, is proportionate, and ends when the attack stops. Vigilantism acts on harm already done and seeks to punish. The line is temporal and functional, not a matter of intensity: it does not depend on how much violence is used.
Why does vigilantism appear?
Criminology consistently associates it with the perceived weakness of institutions rather than the malice of those who practise it. It arises where the police do not arrive, where they arrive and do nothing, or where the population has stopped believing they will act. It is a symptom of a legitimacy deficit.
Why do we like fictional vigilantes?
Because the script builds the vacuum they come to fill before they arrive: the corrupt cop, the bought judge, the system that releases the guilty. By the time the vigilante appears, the viewer has already accepted that there is no institution to trust — which is exactly the mechanism that operates in reality.
