INTRODUCTION

Forensic Architecture research team was formed in 2010 by a group of architects, including Eyal Weizman from Goldsmiths, University of London, collaborating with multi-disciplines1. They investigate national political violence and the violence of military strikes through architectural surveys, Analyze the urban environment and reconstructed architectural models, and simulated scenario animations. Forensis means "in open court" or "public" in Latin, looking for evidence and discussing it openly. Instead of analyzing blood and bones like traditional forensic methods2. Forensic Architecture uses buildings as the principal object of investigation. Weizman pointed out that building form and structure continuously change over time3. He believes that architecture is perceptual and can record changes in different fields, climate change in meteorology, and national politics transformation in international relations4. These buildings' record is the evidence sought in forensics.

The evidence of Forensic Architecture revealed many violent cases that were misjudged or dismissed due to insufficient evidence. These cases are usually entrusted to the Weizman group by NGOs(Non-government organizations) to recollect evidence and bring it to court for retrial. Among these retrials, cases contain government and individual cases as well as the poison gas experiment at Auschwitz concentration camp in World War II5 and racial abuse of black people by police6. Hence, the successfully amended judgment of these cases announced that Forensic Architecture as a discipline could assert itself in antagonistic forums and political directions. Following the introduction, the article is divided into three parts. The first part, "survey," comprehensively describes NGOs working on spatialized modes of investigating state crime. They come from different disciplines and how to collaborate to investigate social issues. In addition, three organizations (from Media; Urban; and Architecture) are described in detail how they collect and organize cases and analyze how they differ from each other in terms of operation or who is the leader in spatial investigation: the first being Bellingcat, represented by journalists, the second by Killing Architects, with a background in urban design, and the third is Forensic Architecture, which is a team of architects. They also demonstrated the "forensic architecture techniques" in their investigation cases, including FA's cross-referencing of digital models and actual footage (pictures, testimonies, videos) to construct the whole event and Killing's incorporation of satellite maps to visualize the data. The second part is "Forensic Architecture Theory". This part introduces the concepts of Forensis; Forum; Evidence; Aesthetics, which are the most important theoretical foundations in Forensic science, and the connections between them, among which Forensis and Forum are both from Roman Latin and have the closest connection therefore The Forensis and Forum are both from Roman Latin and are most closely related, thus they will describe in the same chapter. Additionally this part will use some examples of actual investigation to demonstrate the concept in practice as a fundamental theoretical case study for the third part. In the third part of the thesis: "The Chinese embassy in Belgrade" .This section is the article's core; I will review the 1999 Yugoslav-NATO war. In the late 20th century, the United States carried out armed intervention in Yugoslavia with the support of other NATO allies. Moreover, on the 46nd day of the military strike, the US military bombed the Chinese embassy. This part mainly investigates the deliberate bombing of the embassy by NATO under the political and military violence or the accidental bombing as officially reported by NATO. Since the two sides (China and NATO) did not show enough reports about the incident, there are many constraints and potential problems. Therefore, I will start with previous forensic theories, examine how they were spatially involved in the case, and look for potential evidence rather than trying to "solve" the case to give a definitive answer. Although forensic science and architecture already have independent and sophisticated disciplinary frameworks, this new integrated practice mode also represents a new aesthetics. Architecture transforms the aesthetics of forensics, while forensics evolves architecture into an investigation of spatial materialization.
