The United Kingdom national serious crime squad includes intelligence services, rightly so. It is those sorts of skills that are required because international criminals generally do not give themselves up. There will be a need for covert activity and infiltration to gain information one way or the other. If even a fraction of the allegations currently being made are true, it would cause one to pause for one moment. This could be met by ensuring the protocol for each of the investigations clearly sets out the standards expected, the extent of covert activity, the way in which accomplice evidence is to be dealt with and the dangers of entrapment. It is important we meet the highest standards in this regard.
