Worst Seat in the House

[LincolnMan]

Thanks Roger and Bill - actually I meant to ask exactly the opposite. How often would/does it happen that although the environment nowadays "knows" (observes) someone suffers from traumata, PTSD or similar, a tragedy can NOT be prevented because the person refuses any help/treatment? What does the law say? If someone refuses treatment it's difficult to act upon assumption something could happen, isn't it?

The individuals who refuse treatment have a right to do so. Unless there is imminent danger to themselves or others nothing can be done, generally speaking. As far as how many people there are refusing treatment- that remains unknown.
