at the end of the day he does have to prove that who did it . . .
I think you meant "at the end of the day, he doesn't have to prove who did it".
We hear about mental health issues on the news again, and that GP's are no further on, nor trained in the illness and it's been like this for the past 10 years, which is a disgrace.
Was it specifically in the news that things haven't changed in the last ten years?
We're hearing of young people from their teens to age 30, are taking their lives, for a variety of different reasons, and anti-depressants are being dished out instead of properly diagnosing the type of mental illness ( because nobody is properly trained in this field of medicine )
By definition, at least two things there. A variety of reasons concedes that not everyone (even if fairly young) who ends their own life is mentally ill or on inappropriate drugs.
Because the situation now is the tip of the iceberg,,it was far worse 30 years ago !
Not necessarily, as this is saying it is now far better than it was 30 years ago.
Why has this illness been swept aside for years on end?
Presumably in part because of poor training of GPs in mental health, and in part because of the scarcity and high cost of specialist mental healthcare.
It's responsible for those who take drugs, alcoholics, behavioural problems, self-harm, suicide and of course murder.
That comes across as a sweeping generalization, especially as it makes no mention of other causes and by putting "of course" immediately before "murder" suggests that committing murder is one of the more obvious and natural consequences of being mentally ill, even in comparison with self-harm and suicide.
