Let us be absolutely clear, the attack on innocent people at the Manchester Arena on Monday night was not perpetrated by just one killer.
All those who suspected what he was prepared to do, all those who encouraged or advised him, all those who had just the slightest of worries, all are culpable.
Because it is isn’t just those who commit such horrendous crimes who are guilty. No, it is everyone who in any way connives in their journey to terror.
That is why the calls once again for people to pull together are entirely correct. However, it needs more than just goodwill or cooperation to ensure community cohesion.
