Overall, the essay does a good job of summarizing the current research on the link between mental illness and violence. The author provides a good overview of the evidence, which suggests that there is no clear link between the two. However, the essay does lack a clear conclusion. The author argues that the myth that mental illness leads to violence is not supported by the evidence, but then goes on to say that society should address the negative attitudes towards the mentally ill. This seems to be a bit of a contradiction.
