One unknown factor in the link between crime and mental illness is whether or not mentally ill offenders are more liable than others to arrest. Ninety-one mentally ill, and 76 normal, criminally offending men were asked about the circumstances of their offence and arrest. A majority of mentally ill men had been arrested at the scene of the crime, and more than a quarter of the schizophrenic group had reported themselves to the police. We argue that when many offenders are either unreported or undetected, the increased vulnerability of the mentally ill to detection and arrest makes them disproportionately liable to detection. Attempting to assess the relationship between crime and mental illness is thus extremely difficult.
犯罪与精神疾病之间联系中的一个未知因素是，患有精神疾病的罪犯是否比其他人更易被逮捕。91名患有精神疾病的男性罪犯和76名正常的男性罪犯被问及他们犯罪和被捕的情况。大多数患有精神疾病的男性是在犯罪现场被捕的，超过四分之一的精神分裂症患者组向警方自首。我们认为，当许多罪犯未被举报或未被发现时，精神疾病患者更容易被发现和逮捕，这使得他们在被发现方面的比例过高。因此，试图评估犯罪与精神疾病之间的关系极其困难。
