The root cause is nobody acknowledges that mental illness sometimes reaching a dangerous psychosis is a fact of life greater than a family alone can handle. It must at times be treated with involuntary commitment in a treatment facility and not the county lockup, which is our only option in this day and age.
A jail is better than nothing sometimes, but yes it is sad that there can’t be better.
And this at a time when more and more people are going mad. Drugs. Lies. (Yes, lies drive some people mad.)
