Videotaped Confessions Can Create Bias Against A Suspect

Once you get past the ambiguity of the headline this is a very interesting article from 2007, dealing with the effects of camera angle - "camera-perspective bias":

 

ScienceDaily (Mar. 15, 2007) — Police often videotape interrogations of suspects for use in criminal trials. Video confessions that focus exclusively on the suspect, however, can bias judges and law enforcement officers to consider the suspect’s statements as voluntary, according to a new Ohio University study.

In more than 25 percent of wrongful convictions exonerated by DNA testing, innocent defendants made incriminating statements, delivered outright confessions or pled guilty, according to the Innocence Project. Police interrogation tactics – which include exaggerating the evidence against the suspect or implying the suspect could face an extreme sentence – can prompt a suspect to make a false confession, said Daniel Lassiter, an Ohio University professor of psychology.

In videotaped confessions, many law enforcement agencies focus the camera on only the suspect. Lassiter’s research shows that this practice creates what he calls a camera-perspective bias that leads trial participants to view the confessions as voluntary, regardless of how interrogators obtained them.
