Behavioural Detection Officer.
Spot what a crowd is telling you.
Behavioural detection officers read what a crowd is telling them: the person who does not fit the pattern, the bag left where it should not be, the questions that are not really questions. It is a trained skill, built on baselines and indicators rather than instinct, and it is moving to the centre of venue security as Martyn's Law arrives. For licence holders it is the specialism that separates a CV from the pile.
