Daniele Vicari’s film “Diaz – Don’t Clean Up This Blood” examines the violent 1978 Rebibbia prison riot in Rome, reconstructing a period of intense civil unrest and systemic police misconduct in Italy. The film, which premiered at the 81st Venice International Film Festival in 2024, uses the historical event to explore themes of institutional accountability, human rights, and the long-term physical and psychological trauma resulting from state-sanctioned violence.
The narrative centers on the September 1978 crackdown at the Rebibbia prison, where a prisoner uprising led to a brutal response by law enforcement. By dramatizing these events, Vicari attempts to address what many historians and human rights advocates describe as an “open wound” in the Italian judicial and penal history. The film focuses not only on the immediate chaos of the riot but also on the subsequent efforts to uncover the truth behind the injuries and deaths that occurred during the intervention.
As medical professionals and public health experts observe, events of this nature leave lasting scars on the social fabric and the individual health of those involved. The film serves as a cinematic inquiry into how institutional failures can lead to mass trauma, a topic that remains relevant in modern discussions regarding prison reform and the regulation of police force globally.
What was the 1978 Rebibbia prison riot?
The events depicted in “Diaz – Don’t Clean Up This Blood” are rooted in the historical reality of the “Years of Lead” (Anni di piombo), a period of intense political violence and social unrest in Italy during the 1970s. In September 1978, tensions within the Rebibbia prison in Rome escalated into a full-scale riot, driven by prisoner grievances regarding living conditions and systemic mismanagement.
According to historical records of the period, the subsequent police intervention was marked by significant violence. The riot was not merely a localized disturbance but part of a broader era of instability within Italian state institutions. The film portrays the descent from controlled incarceration to a chaotic environment where the lines between maintaining order and committing human rights abuses became blurred.
The historical context of 1978 is essential to understanding the film’s urgency. During this time, Italy faced frequent confrontations between state authorities and various political factions. The Rebibbia incident became a symbol of the friction between the state’s duty to maintain security and its obligation to uphold the fundamental rights of those in its custody.
How does Daniele Vicari depict institutional violence?
Director Daniele Vicari utilizes a visceral, documentary-style approach to capture the claustrophobia and terror of the prison environment. Rather than relying on stylized action, the film focuses on the sensory details of the riot—the sounds of metal on concrete, the chaotic movement of bodies in tight spaces, and the abruptness of the violence. This method aims to strip away the cinematic veneer, forcing the audience to confront the raw reality of the event.

Critics at the Venice International Film Festival have noted that Vicari’s direction emphasizes the “unseen” aspects of the riot: the moments of decision-making by officers and the immediate, often devastating, physical consequences for the inmates. The film’s title, “Don’t Clean Up This Blood,” serves as a metaphor for the refusal to sanitize or ignore the historical evidence of these abuses.
By focusing on the granular details of the crackdown, the film highlights the breakdown of institutional protocols. The narrative suggests that the violence was not an accidental byproduct of a riot, but a systemic failure that allowed for unchecked aggression. This focus on the mechanics of violence provides a framework for discussing how institutional culture can influence individual behavior during high-stress operations.
The physical and psychological toll of mass institutional trauma
From a public health and medical perspective, the events portrayed in the film represent more than a political or historical milestone; they represent a significant incident of mass physical and psychological trauma. In environments like the Rebibbia prison, where space is limited and medical oversight can be inconsistent, the impact of sudden, large-scale violence is compounded.

The physical injuries sustained during such riots—ranging from blunt force trauma to respiratory distress caused by crowd control measures—often require intensive medical intervention. However, the long-term health implications extend far beyond immediate physical wounds. Medical literature on institutional violence frequently identifies several key areas of concern:
- Acute Stress Disorder and PTSD: Both inmates and responding officers are at high risk for Post-Traumatic Stress Disorder (PTSD) following high-intensity violent encounters.
- Chronic Physical Sequelae: Injuries sustained during unrest can lead to long-term mobility issues, chronic pain, and secondary health complications.
- Institutional Distrust: Frequent exposure to violence within the penal system can lead to a breakdown in the patient-provider relationship, making inmates less likely to seek necessary medical care.
The film captures the immediate terror of these injuries, but the underlying medical reality is that the “wound” mentioned by critics is both physical and psychological. For the survivors, the trauma of the 1978 riot is not a closed chapter but a continuous factor in their long-term health and social integration.
Legal and human rights implications of the Rebibbia incident
The aftermath of the Rebibbia riot involved complex legal battles aimed at determining the extent of police misconduct. The film mirrors the real-world struggle to hold authorities accountable for the actions taken during the intervention. In many jurisdictions, the legal distinction between “necessary force” and “excessive force” is a central point of contention in cases involving prison riots.
Human rights organizations have frequently used historical precedents like the Rebibbia incident to advocate for stricter oversight of correctional facilities. The ability of the state to monitor and report on the use of force within closed institutions is considered a cornerstone of modern human rights law. When transparency is lacking, the risk of unpunished abuse increases, creating a cycle of violence and distrust.
The film underscores the difficulty of achieving justice decades after the fact. It highlights how the passage of time can erode evidence and how the institutional memory of such events is often subject to political revisionism. The struggle for truth in the wake of the 1978 riot remains a significant aspect of the Italian legal and social landscape.

Why the film matters for modern social discourse
While “Diaz – Don’t Clean Up This Blood” is a historical drama, its themes resonate with contemporary debates regarding the ethics of policing and the management of incarcerated populations. As many countries face rising scrutiny over prison conditions and the use of force by law enforcement, Vicari’s work provides a sobering reminder of the consequences of institutional opacity.
The film also contributes to the broader movement of “historical memory” in European cinema, where filmmakers use the medium to preserve truths that might otherwise be lost to political shifts. By bringing the 1978 Rebibbia riot to a modern audience, the film ensures that the victims and the systemic failures of the era remain part of the public consciousness.
For viewers and scholars alike, the film serves as a case study in how cinema can function as a tool for social inquiry. It asks not just what happened, but why it was allowed to happen, and what the cost of silence has been for the survivors and the state.
The next significant milestone for the film will be its wider theatrical distribution and subsequent critical reviews in international markets. We will continue to monitor updates regarding its release and any related scholarly or legal discussions sparked by its debut.
