What the what? What fresh police quackery is this?
VSA is just like the polygraph. It’s a pseudo scientific test that really takes advantage of most humans subconscious desire to be truthful. You can’t read the graph, most regular people can’t read it either, but the police tell you this is backed by science and they just need to convince the subject they “know” they are lying so they confess. The science is weak, depends on loose interpretation of the human body, is not the same results from human to human or even same human multiple sessions. Oh and wholly depends on the subject feeling guilty and wanting to confess. Helps when they are heavy religious too.

Yeah. They used pseudoscience to trick someone into confessing. Just as lie detectors aren’t admissible in court it doesn’t prevent them from being used as a means of coercion.
