“Historically the official stakeholders in the criminal justice system, politicians, judiciary, bench, bar and law enforcement agencies, have taken great pride in the near-certain infallibility of the adversarial system of criminal justice. Today the rising tide of post-conviction DNA exonerations has shed a harsh and unflattering light on the staples of classic investigative tools and trial evidence: investigative and prosecutorial tunnel vision, eye-witness fallibility, hair and fibre junk science, opportunistic jailhouse informants, self-induced and other induced false confessions and disclosure failures. These classic tools, alone and in combination, have been the cause of numerous wrongful convictions.” Richard Wolson “Tough Crimes”
