As part of our inaugural lecture series, Rebecca Wexler, a founding director and instructor for the Yale Visual Law Project, discussed the relationship between documentary photography and the law. In doing so, she challenged the seemingly evidentiary nature of digital images in the courtroom and questioned the ethics of using proprietary software as an investigative tool.
Wexler opened with the image of a man lying motionless in a field, his white shirt covered in blood. It was one of many that had been investigated by the UN as evidence of genocide, and it was produced by a software program that isolated still images from video footage. The program, she explained, can create still mosaics and run velocity calculations based on an object’s movement from one frame to the next. However, she noted that the use of this program allowed investigators to come to one, and only one, conclusion: “There is a red stain on the man’s shirt."
Ironically, Wexler pointed out that another team of investigators were able to reach the same conclusion without manipulating the footage: “The man’s shirt has a red stain on it.” Regardless of their outcomes, however, she argued that the analysis of differently rendered versions of the same piece of evidence should cast doubt on conclusions made by either side – in this case and others.
Towards the end of her lecture, Wexler argued for a reexamination of the plain view precedent, arguing that it doesn’t necessarily authorize “the seizure of potentially incriminating data through photographic images.” First, she reiterated that images can be enlarged or enhanced in to reveal information that is not necessarily evident to the naked eye, which makes them more than observational in nature. Then, she emphasized that the increased use of body cameras in homes or privacy-protected spaces problematizes the issue because they may be “trying to incriminate events that haven’t happened” or that may only be revealed in retrospect.
In closing, Wexler paused to address how the collection of metadata, including GPS coordinates, may be used to not only authenticate data but also present a potential risk to anonymous sources. Unfortunately, she noted that the Supreme Court has largely neglected to address issues of privacy and authenticity in relation to digital photography and the Fourth Amendment, leaving them up to the lower courts to decide on a case by case basis.
