Eyewitness testimony is a common form of evidence in the legal system. People generally identify suspects based on characteristics such as their appearance, clothes, voice, and even writing style. But what if you could identify someone based on the way they move (e.g., the way in which they walk)? To determine if identification based on movement would be practical and legally allowed, I examined the legal implications of identification that pertain to the Fifth Amendment, as well as the appropriate scientific applicability test based on movement. I also conducted an experiment to evaluate the reliability of such identifications based on movement.
