Truly, the great thing about Britain is how we always learn from our mistakes.
After the accidental shooting eight times of Jean-Charles De Menezes in 2005, the Metropolitan Police accepted that it needed to urgently revise its anti-terror strategies, and did so.
Today's announcement by the Independent Police Complaints Commission noted that the Metropolitan Police made several errors during an operation in Forest Gate last year. Errors included accidentally arresting eleven innocent people, accidentally shooting an innocent man through the shoulder and accidentally smearing one of the victims as a closet paedophile.
Well, accidents happen, and the Met have been big enough to admit their mistakes. I have my contacts, and I'm glad to say that I've managed to procure a copy of the coppers' revised guidelines for anti-terror operations...
