Is is going to help society (or the disordered individual) to treat that dysfunctional person with bipolar, ptsd, narcissicm, or one of the many other possible personality or mental disorders as a criminal?

I understand that lay people can't 'diagnose' but as a landlord, you can save yourself a lot of grief by being informed about the different types of personality disorders and recognizing the signs-- especially of the cluster B disorders.

For example, the document that Phil provided states what mental disorder is being treated.

Him: bi-polar disorder.

But from my research, you can not disqualify someone for drugs or alcohol felonies because it is considered a "mental health disorder" You can always find another reason not to rent that doesn't have anything to do with that. :)

Los Angeles County, CIty of Signal HIllTenant with anxiety disorder presented with prescription from physician for daily medical cannabis inhalation.My first thought was, 'is that without filters by any chance?'

@Lucas Carl The only tenant I ever had that rose to that level of crazy was NPD (narcissistic personality disorder); he actually told me that-- and I believe it because he had all the symptoms.

(who is not a licensed mental health professional) that her young son has attention deficit disorder and a service animal would mitigate the symptoms he is experiencing. 

I seriously believe she has some sort of obsessive disorder or something, but maybe a letter from an attorney might correct the behavior.

He was either Bi-Polar 1, Schizophrenic, or was suffering from dellusions from too much Meth.
