Under codified legal systems such as France, torture was superseded with a legal system that is highly dependent on investigating magistrates and the confession remains "The Queen of Proofs". Such magistrates are often under pressure to produce results. It is alleged that in many cases police violence towards suspects has been ignored by the magistrates. In the adversarial system of common law used throughout the English-speaking world, the experience is a different one. As the two parties have to convince a jury whether the defendant in a case is guilty or innocent of a crime, if the defence can persuade a jury that reasonable doubt exists over the credibility of a confession, then the jury is likely to disregard the confession. If the defence can show that the confession was made under such duress that most people would make such a confession, then the jury is likely to question the confession's credibility. Usually the more duress that can be shown to have been used by law enforcement by the defence, the less weight most juries will place on confessions. In Britain, partly to protect the individual against police brutality and partly to make confessions credible to a jury, all interviews with a suspect are audio taped on a machine which make two simultaneous copies, one for the police and one for the defendant. In Northern Ireland, where society is more polarised than in the rest of the United Kingdom, which means that allegations of police brutality are perceived by sections of the community to carry more credence, interviews are video taped.
