TheBigRetort has always found calls for the resignation of the Commissioner of the Metropolitan Police to be unwarranted.
If heads should roll they should fall lower down the ranks.
However, it was part of Sir Ian's statement to the press following calls for his resignation that pricked our ears.
Sir Ian ended his statement, with the following - curious? - paragraph:
"A report published this morning also revealed that none of the 17 members of the public on board the train recalled hearing officers shout "armed police" prior to killing Mr de Menezes, even though all eight police in the carriage claimed they had."
The question is why the Commissioner needs us to know this.
