Incident in a police state

Is the state guilty of child kidnap? - Telegraph: '[...] on May 18, when Mr and Mrs Jones, accompanied by their younger son, arrived at school to pick up their daughter, they were met by a group of strangers, one as it turned out a female social worker. She asked, without explaining why or who she was, whether he was Mr Jones. When she three times refused to show him any ID, he was seized from behind by two policemen, handcuffed and put under arrest. ... He was driven by a policeman to a nearby mental hospital where he was told that, because of "a number of concerns", he was being detained under Section 136 of the Mental Health Act and "sectioned" under S.2 as of "unsound mind". His wife, it turned out, had been similarly arrested, for loudly protesting at the handcuffing of her husband and the forcible seizing from her arms of her young son. The three children had been taken into care by social services. ... Mrs Jones was allowed to return to an empty home that evening. Mr Jones was permitted to attend court two days later, to hear the magistrates grant an interim order for the children to remain in the care of social services. Because he was "sectioned", he was not allowed to speak. The chief magistrate, it later emerged, was chairman of the trustees of the mental hospital in which he was being detained.'

And what was his "mental illness" - perceived delusions of grandeur and paranoia about the safety of his children?
