This chapter examines four common immediate causes of wrongful convictions as confirmed by recent data from registries. They are mistaken eyewitness identification, incentivized and lying witnesses, false confessions and faulty forensics. Commonly used remedies designed to prevent these immediate causes are examined from a legal process perspective, which stresses the different remedies that can be implemented by courts, legislatures and through executive measures. The latter includes reforms that police and forensic science providers can take themselves to decrease the risk of causing wrongful convictions. The most effective strategies often involve all three branches of government. At the same time, many jurisdictions are reluctant to adopt optimal reform measures because of concerns about preventing the use of evidence that is frequently used to achieve convictions. For example, the use of jailhouse informants has not been banned despite their frequent role in wrongful convictions. This insight suggests that reforms to prevent wrongful conviction cannot ignore their perceived or likely impact on conviction rates.
