Radio Sheffield just said about how those with drug addiction like the latemay be mentally ill but due to civil liberties if is illegal to put them in a straitjacket. Amy, despite her fame, may have felt few cared for her. If seen as disturbed she may have felt society loved her for her fame, but personally some may say she did not deserve full medical rights for what she did to herself.
Society discriminates to those seen as different. Mental health deaths that are suspect are often not seen as worth bothering about by the police, as much as they bother about the deaths of those who are socially high profile and solvent.
In such cases it is easier to kill a mentally ill person than it is to kill a well balanced person. It is possible for suspect NHS staff to think they can remove food and water from mentally ill and degrade human rights and even use such wards as places of moral punition for victims.
Weaker people are often seen as priviliged to participate in a permissive world. Yet in the eyes of God we are all equal. Anyone reasonably humane would say mentally ill people are not being wise, but may be disadvantaged not due to their own fault. They may be injustly left out of jobs for instance, causing stress or depression, or bullied, and as such should not be given less right to life than others.
It will take a long time for some professionals and police to learn this. That is a sad fact of a broken society.
