Did anyone ask, when she verbalised suicidal thoughts, if she "had a plan", I wonder?
If she did have a plan, she should have been detained for assessment / sectioned.
In the aftermath of suicides, everyone finds reasons to blame themselves/ask themselves whether they could have done more. However, the fact is that the decision lies with the individual and that it can only be their responsibility.
Everything else - press, police, medical staff - is just a distraction from that fact.
