Going back to finish the story behind the weaponise thread, the guys with the ricin apparently went to Manchester and, as a result of ‘intelligence’, the police went to arrest what they were told was one guy. Turned out there were three one of whom broke free, got hold of a carving knife, killed one policeman and injured three others before being subdued. Seems the one who died was a detective and they do not usually wear body armour. I guess had there been just the one he wouldn’t have got into the action.

This word 'intelligence' seems misapplied sometimes.
