Marks out of 10?

Considerable embarrassment has been caused to Scotland Yard by the revelation that one of their anti-terrorist advisers is himself wanted by Interpol for alleged past terrorist activities. Whether or not under these circumstances he should ever have been appointed in the first place is one question, but his suitability to remain in his post now that this is known is, I would suggest, more a matter of how well he is and has been doing the job. After all, don't forget the old adage "Set a thief to catch a thief".
