in order to get a better insight into the effects of mental health services and its benefits, we have to look into mental health cases in the united states from criminals over the past years. the relationship between psychiatric illness and criminality has been the topic of intense debate. over the years multiple mass shootings in the united states have happened . the popular belief is that people with mental illness are more prone to commit acts of violence and aggression. the public perception of a mentally ill patient is portrayed as a dangerous individual. a large body of data suggests otherwise. people with mental illness are more likely to be a victim of violent crime than the perpetrator. this bias extends all the way to the criminal justice system, where persons with mental illness get treated as criminals, arrested, charged, and jailed for a longer time in jail compared to the general population.
