Yes, the stabbing IS about immigration Britain needs an honest conversation about the high degree of mental illness in certain ethnic communities Black people are 4 x more likely to be detained under the Mental Health Act than whites Black men are more likely to have had a psychotic disorder in the last year than white men Black people are diagnosed with schizophrenia at a rate of approximately 2.4 to 4 times higher than white people Asylum seekers have more mental health problems than the native population British Pakistanis account for 3% of births but 33% of children with genetic birth defects. Why we are importing so many people who are a risk to the safety of others, contribute hugely to anti-social behaviour on our streets and are a burden on our failing mental health services? It appears to be one of the few remaining taboos no one is willing to address. From the murder of the Ukrainian woman in a American train to the mass stabbing on the Huntingdon train - to the daily evidence we see on the streets of our biggest cities - the mental health crisis within black and certain other communities is an issue we can no longer ignore. We must have this conversation urgently without fear of causing offence. British lives depend on it.
