Relationship between crime and mental disorder
Mental disorders have been related to crime and are being depicted over the media as dangerous and unpredictable (Tartakovsky, 2012). Pullman (2010) did an analysis of 211 females and 212 males that were in medical care and also had criminal charges. The study aimed to find the relationship between mental health and the transition from adolescent to adulthood (16 – 25 yrs) which is the most common offense period. Their findings were that the odds of being charged for a violent crime was increase by five times for those with conduct disorder, more than five times for substance use disorder and nine times for those with developmental disorders. So it’s no wonder that researchers are interested to find out if this is true. A crime is only a crime when society’s law is broken. Of which Seigel (2008) describes it as “Crime is a violation of societal rules of behaviour as interpreted and expressed by the criminal law, which reflects public opinion, traditional values and the viewpoint of people currently holding social and political power.” So knowing what a crime is, we have to know what classifies as a mental disorder. Kendell (2002) states that the World Health Organisation have avoided defining “diseases”, “illnesses” and “disorders” as it simply states ‘the term disorder is used throughout the classification, so as to avoid even greater problems inherent in the use of terms such as disease and illness, Disorder is not an exact term, but it is used here to imply the existence of a clinically recognisable set of symptoms or behaviour associated in most cases with distress and with interference with personal functions.’ Due to the existence of many mental disorders, this paper aims to find any and all relationships surrounding those suffering from schizophrenia. It will cover points such as how dangerous schizophrenic patients are as compared to general population, impulsivity in them, subgroups in schizophrenic patients in sexual or violent offense, influence of comorbidity, early versus late onset of schizophrenia, and finally victimization. To understand the relationship between schizophrenia and crime, we must first know how schizophrenia is a disorder. For the sake of this paper, there is only the need to explain the positive symptoms of schizophrenia, which are faulty sensory interpretations such as hallucinations, delusions and thought disorder. These are known as psychotic drives which will be discussed in the later sections.

Level of risk
Mullen et.al. (2000) had findings that support the notion that those with schizophrenia were more likely to offend. They also found that they were not as likely to sexually offend as compared to their other offences such as violence, property damage and drug related offences. Eriksson (2008) have also found similar results through various literature review where those with schizophrenia were twice to seven times more likely to offend violently. Impulsivity in Schizophrenic patients

Enticott and colleagues (2008) have found that impulsivity have been known to be linked to violence. Their participants are from a secure psychiatric facility (n=18) and were compared to healthy participants (n=18) where there were more males...
