Finally, I want to address those members of the community from where this killer came who knew him and did nothing to raise any alarm bells.

Oh, I guess it’s possible he just woke up one day and decided to mass murder children.

But let’s work on the far more likely assumption that he became more and more deeply radicalised by Muslim extremists both in Britain and aboard.

He is someone’s son, someone’s friend, possibly someone’s work colleague.

Did anything change about his behaviour?

Did he suddenly start spouting demented claptrap about Islamic State and their plan for a global caliphate?

Did he say or do anything to arouse suspicion? I’ve no idea.

But I refuse to believe this disgusting excuse for a human being never gave a single clue to anyone around him that he was becoming radicalized.
