I started this thread then went to bed, sorry.
I don't blame police officers, they are working within a system and have to comply with its restraints.
I don't blame hospital staff, I was a nurse and know that medical staff are, most of the time, staving off crisis-point rather than giving optimal care.
However, it's a crying shame when someone says "I need to be sectioned. The last time I felt like this I killed someone. I think I'm going to kill again", that nothing can be done to protect the public and save the perpetrator from herself.
We say 'you can't detain someone because they might do something', but actually you can, if the laws allow it.
For instance, a drunk person would be arrested if they were in charge of a motor vehicle. They don't have to be behind the wheel, nor with the engine on. It's the law.
Someone who has been highly antisocial can have constraints put on them to prevent further antisocial behaviour.
Someone who had been convicted of offences toward or involving children can be prevented from working with them.
There should be something in place which takes a person who fears they will kill as they have killed before in similar times, to a place of safety for evaluation.
The biggest tragedy was that an indefinite sentence lasted just 3 years. She would have been detained longer if found guilty of murder and I can't help thinking that's why the judge found as he did. He knew that if he accepted diminished responsibility she'd be out to do it all again in 3 years.
Rinse and repeat
