Im with warren on this, although its awful what has happened to the poor guy who got hurt, he was simply in the wrong place at the wrong time, but if anyone is to blame its the inadequateness of the nhs's mental health departments around the country, they are simply not equipped to cope with the volume of patients there are,
I have first hand experience of this as i deal with my wife who is bi-polar with borderline personality disorder thrown in for good measure, very recently she was "in crisis" and it took us nearly 3 weeks to get to see the consultant, for 2 of those 3 weeks the regular telephone number for my wifes consultant went straight to answer phone because the demand was so high on the outdated telephone system, we contacted the so called crisis team and they were to busy and to far away from the village we live in to be of any use.
when we do finally manage to get to see the consultant all she can really do is try and talk through why she is feeling the way she is at the moment whether that be that she is "manic" or depressed or even angry, and try to adjust the medication she is taking to suit the current mood, all this is because the resources my wife really need are so over streched, she has been waiting 3 years to get to see a councillor, and 8 months for a cpn who can help her manage the way she feels till a different resource becomes available.
