The trial of four Indonesian soldiers in Medan marks a rare moment of judicial scrutiny for the country’s powerful military establishment. These men stand accused of a calculated acid attack against Persada Bhayangkara Sembiring, an investigative journalist whose work centered on the murky world of illegal gambling. While the courtroom proceedings focus on the logistics of the assault, the case serves as a grim barometer for press freedom and the reach of military impunity in Southeast Asia’s largest democracy. This is not merely a local criminal dispute. It is a violent intersection where organized crime, military discipline, and the public’s right to know collide with devastating force.
The attack occurred in July 2021, but its reverberations are only now reaching a legal climax. Sembiring was doused with sulfuric acid, a chemical chosen specifically for its ability to maim and silence without immediately killing. This choice of weapon suggests a specific intent to terrorize rather than a momentary lapse in judgment. The prosecution alleges that the soldiers acted as hired muscle, bridging the gap between underworld interests and physical enforcement.
The Mechanics of a Contracted Assault
To understand why military personnel were allegedly involved, one must look at the local power structures in North Sumatra. The region has long struggled with "backing"—a term used to describe the protection provided by security forces to illicit businesses. In this instance, the victim had been reporting on a local gambling den. When a journalist refuses to be bought, the next step in the escalation ladder is often physical intimidation.
The logistics of the attack were precise. Surveillance footage and witness testimony suggest the perpetrators tracked Sembiring’s movements for days. They knew his route. They knew his habits. This level of reconnaissance is a hallmark of professional training, redirected here toward a civilian target. By using acid, the attackers ensured that Sembiring would carry a permanent, visible reminder of the cost of his defiance. It is a form of psychological warfare played out on human skin.
The Problem with Military Courts
Indonesia’s legal system contains a significant hurdle for those seeking justice against the armed forces (TNI). Personnel are typically tried in military courts, not civilian ones. Critics and human rights advocates argue that this parallel justice system often acts as a shield. The lack of transparency in these proceedings frequently leads to lenient sentencing or the complete disappearance of high-ranking commanders from the charge sheet.
In the Medan case, the four soldiers occupy the lower rinks of the hierarchy. While their prosecution is a step forward, it leaves the "intellectual actors"—those who paid for the hit—comfortably in the shadows. A private, a corporal, or even a sergeant rarely initiates an acid attack on a journalist of their own volition. They are tools. Until the chain of command or the financial benefactors are brought into the light, the trial remains an exercise in trimming the branches while the roots remain healthy.
A Pattern of Targeted Violence
The assault on Sembiring is part of a broader, more troubling trend in Indonesia. According to data from the Alliance of Independent Journalists (AJI), violence against media workers remains stubbornly high, with the perpetrators frequently identified as members of the security forces. The "why" is simple: the press is the only entity consistently poking the hornet's nest of illegal mining, logging, and gambling.
When a soldier is the aggressor, the power imbalance is absolute. The victim isn't just fighting a criminal; they are fighting an institution. This creates a chilling effect that extends far beyond a single newsroom in Medan. Other journalists see the scars, they see the slow-moving military trial, and they think twice before publishing that next exposé.
Chemical Weapons in Civil Society
The use of acid is a specific choice that demands scrutiny. Unlike a shooting or a stabbing, an acid attack is designed for maximum public spectacle. It is slow. It is agonizing. It requires long-term medical intervention and results in permanent disfigurement. In many parts of the world, acid attacks are gendered crimes, but in the context of Indonesian corruption, they have become a tool of political and professional censorship.
The availability of these chemicals is another factor. Industrial-grade sulfuric acid is relatively easy to obtain in regions dominated by mining and manufacturing. There is little to no tracking of these substances. This lack of regulation provides a low-cost, high-impact weapon for those looking to settle scores without the noise of a firearm.
The International Stake
Global observers and human rights organizations are watching this trial because it tests the promises made by the Indonesian government regarding military reform. Since the fall of the New Order regime, the TNI has been under pressure to stay out of civilian affairs and focus on external defense. However, the involvement of soldiers in the protection of gambling rings and the subsequent assault on a journalist suggests that the old habits of the "dual function" era haven't entirely faded.
Foreign investment and diplomatic relations are often tied to the "rule of law." When a country cannot guarantee the safety of its journalists or the accountability of its soldiers, it becomes a riskier environment for international engagement. The credibility of the state is currently sitting in that Medan courtroom.
The Survivor’s Burden
For Persada Sembiring, the trial is a secondary battle. The primary battle is the recovery from extensive chemical burns that required multiple surgeries. He has been forced to navigate a health system that is often ill-equipped for the complexities of acid-related trauma. Beyond the physical pain, there is the social stigma and the constant threat of retaliation.
The defense has attempted to poke holes in his testimony, a standard tactic aimed at discrediting the victim. They suggest personal motives or mistaken identity. These arguments fall flat when confronted with the evidence of coordinated movement and the specific timing of the attack following his reports on the gambling dens.
Breaking the Cycle of Impunity
Justice in this case requires more than just a guilty verdict for four men. It requires a fundamental shift in how the Indonesian state handles crimes committed by its uniformed officers.
- Civilian Oversight: There is a growing demand for military personnel to be subject to civilian criminal law when the victim is a civilian. This would remove the perception of "soldiers judging soldiers."
- Protection for Whistleblowers: Journalists working in high-risk regions like North Sumatra need a robust protection framework that doesn't rely on the very agencies that might be targeting them.
- Financial Audits: Investigating the money trail of the gambling dens involved would likely reveal why these soldiers felt comfortable acting as mercenaries.
The trial of these four soldiers is a symptom of a deeper infection. If the court settles for punishing the foot soldiers while ignoring the architects of the violence, it reinforces the message that the powerful can buy silence with a bottle of acid. The scars on Sembiring's face are not just his own; they are the scars of a democracy struggling to hold its guardians to account. The final verdict will determine if those scars lead to healing or further decay.
