We have had a couple of deaths in/near where I live involving individuals with mental health issues, usually described as bipolar in the papers. Two of these deaths happened when the person with MI attacked the police. An interesting tidbit was attached to the end of the articles... something like "he was under the influence of meth". Meth is known to cause violence, not bipolar. People with bipolar are more likely to be victims of violence than the person being violent.
