If it turns out that the intelligence services and the police have indeed foiled a plot to commit mass murder on a scale never before seen in the UK – and I have no reason to believe that it won't – then we owe them our thanks and gratitude.
We are quick to criticize when things go wrong, such as the killing of Jean Charles de Menezes and the shooting of Mohammed Abdul Kahar in Forest Gate in June. Perhaps I am reading a biased sample blogs, but I have not seen a corresponding flurry of recognition of the success of intelligence gathering, investigation and international cooperation that has prevented the destruction in mid-air of nine passenger aircraft.
Similarly, in today's FT, there is a grudging editorial, complaining about the disruption at the airports and recalling past errors: there is no hint of congratulations for the success that the law enforcement agencies have achieved. Nor does today's Guardian leader offer any thanks.
Well I think that is humbug. Well done, men and women of the law enforcement agencies. We owe you.
