I hold no brief for Sir Philip Green. What I hear about him, I dont like. But I dont know how far he has gone too far, or how different he is from those who don't get found out. At the same time I dont think that the campaign to strip him of his knighthood is quite hitting the right target. I am not sure that honours, if they should be awarded at all, should be awarded provisionally, on condition of good future behaviour.
For a start, there is the randomness of the 'finding out" principle, or the intermittent rule changes. However immoral or unworthy Sir Philip may have been, I bet there are, or have been, quite a few others who have turned out to be just as unworthy but have not been found out. In fact, I seem to remember, Lord Archer only escaped because of the timing of the rule change that made forfeiting an honour a more feasible procedure. But more to the point, are the principles and practices of the honours system, and the due diligence required in making sure that gongs are not given to 'the inappropriate'.
