Book excerpt: The case of Jessica Kumala Wongso garnered significant attention due to its complex and contentious nature. It began with the mysterious death of Mirna Salihin, who collapsed and died shortly after consuming a coffee at a café in Jakarta, Indonesia, in January 2016. Jessica Kumala Wongso, a close friend of Mirna, was accused of poisoning her with cyanide-laced coffee, leading to her arrest and subsequent trial. The trial unfolded with intense scrutiny from the media and the public, as well as heated debates surrounding the evidence presented. The prosecution argued that Jessica had a motive to harm Mirna due to personal conflicts, while the defense contended that there was insufficient evidence to prove Jessica's guilt beyond a reasonable doubt. The case delved into various aspects, including forensic analysis of CCTV footage, witness testimonies, and expert opinions, further complicating the legal proceedings. After a lengthy trial spanning several months, Jessica Kumala Wongso was ultimately convicted of premeditated murder and sentenced to 20 years in prison in October 2016. The case sparked widespread discussions about the reliability of forensic evidence, the integrity of legal proceedings, and the role of the media in shaping public perception. Despite the verdict, the case continues to be a subject of controversy and debate, with many questioning the fairness and transparency of the trial process. The manipulation of Café Olivier's CCTV footage through downscaling played a pivotal role in the legal proceedings of Jessica Wongso's case. Downscaling refers to the deliberate reduction of the video's resolution, from a higher resolution 1920x1080 pixels (1080P) to a lower one 960x576 pixels (960H). Throughout the trial, forensic experts, including those appointed by Wongso's defense team, revealed how this manipulation technique obscured crucial details and compromised the integrity of the evidence presented. As the trial unfolded, it became evident that the downscaling of CCTV footage significantly impacted the perception of events. The reduced resolution made it challenging for the court to discern specific actions or movements, leading to debates over the accuracy and reliability of the footage. Moreover, the discrepancies introduced by downscaling raised doubts about the prosecution's narrative and highlighted the need for comprehensive forensic analysis to uncover the truth. Ultimately, the revelation of digital tampering through downscaling became a focal point of Wongso's defense strategy. By exposing the manipulation of evidence, Wongso's legal team aimed to cast doubt on the prosecution's case and challenge the credibility of the allegations against her. The downscaling of CCTV footage emerged as a critical factor in the trial's proceedings, underscoring the importance of technological expertise and forensic scrutiny in the pursuit of justice. From my perspective, addressing an international audience, it is paramount to shed light on one of the most egregious instances of digital manipulation and tampering witnessed in recent history. This pertains to the CCTV footage from Café Olivier, which has been subjected to a series of calculated alterations by two individuals acting as digital forensic experts within the Indonesian police force: Muhammad Nuh Al-Azhar and Christopher Hariman Rianto. Their actions constitute a flagrant disregard for truth and justice, warranting a comprehensive examination to uncover the extent of their deceit and the repercussions thereof. The manipulation of CCTV footage from Café Olivier represents a brazen attempt to distort reality and obfuscate the truth. Through their purported expertise in digital forensics, Muhammad Nuh Al-Azhar and Christopher Hariman Rianto orchestrated a meticulous campaign of alteration, wherein crucial details and events within the footage were systematically tampered with or omitted altogether. This manipulation extends beyond mere technical adjustments; it undermines the integrity of the entire legal process and threatens the very foundation of justice.
