Er, what reputation? How can it possibly be damaged any further? This is the same force that shot dead Jean Charles De Menezes, and then lied about the circumstances leading up to his death. This is also the same force that caused the death of Ian Tomlinson, and denied having any contact with him.
In both instances the Police only changed their story when video evidence came to light which was completely at odds with what the Metropolitan Police claimed had happened. You have no reputation to defend, lying scumbags.
