Originally I thought it has something to do with architecture, e.g. architectural design to prevent crimes and protect human rights. The book was not as architectural as I expected, but a nice one.
Forensic Architecture, itself also the name of a group the author founded, is about a forensic study using the architectural understanding. The group also uses media and scientific facts to pursue the idea (actually I felt the architectural expertise contributes only partially to their work). The British-Israeli author starts the book from how the architectural understanding helped to counter Holocaust denial arguments and then spends an entire chapter about injustice and human rights violations in Palestine (due to that this book is quite infamous among some Israelis).
I believe we should use this sort of scientific approaches more to deal with disputes where individuals’ testimonies are being the only source to derive the conclusion. What came to me first and foremost is that we can use the expertise to solve the long-lasting “Comfort Women” issue in East Asia.
