Despite media speculation, there is no proof that the Met itself has called for his resignation. Indeed “Sir Ian Blair…denied he was being ousted from his job”(2)
His contract will not end until 2010 and so for that has been uncontested.

What happened with Jean Charles de Menezes should have been dealt with earlier on, and should not be brought up time and time again. The subject is now outdated and that one cannot possibly punish him so late on as it will not set an example, but perhaps signify the incompetence of our justice system.

Sir Ian Blair is doing vital work at the MPS in moving them to a community-orientated police service. In Brazil, it is a matter of fact, that if such similar instances had occurred, we would definitely not have heard about it. Also, the fact that we broadly criticise and threaten to make him resign arguably plays into the hands of the terrorists. This is what they want! They want us to fear and pick holes in ourselves so that we weaken from the inside as a society so that they need to do limited damage to the outer-shell.

Indeed Ian Blair has made grave blunders that should arguably cause him his office but I am reluctant to agree that his resignation is the way out as I feel the media has in fact blown the issues out of proportion. The media hype on Ian Blair’s blunders has triggered an emotional rather than intellectual response amongst public. The papers are quick to put up the bad points but refuse to advertise his good achievements like the fact that since he took the office of Met Chief Commissioner in 2005 there has been an 18% reduction in crime (1) or how he has survived and managed to keep London reasonable safe in the height of terrorist attacks. He must have been good for something or else he would not have been appointed. Ian Blair has undisputedly faced a difficult tenure especially with the constant ramblings of the media and if he is replaced prematurely I am very reluctant to believe that his replacement will do a significantly better job. Perhaps the difference will be that he may not make the same mistakes as Ian Blair but he will surely make his own mistakes and in such difficult times, these mistakes are certainly not far off. The truth of the matter is we all make mistakes, however the most important issue is that we learn from them. The solution is not to kick him out but to learn from his mistakes and attempt to correct them if we can, after all we already kicked one Blair out and that has not made the decision to go to Iraq any better.

There are three standing allegations that could cause Blair his office at the moment. The Stockwell investigation, the racial discrimination allegation and the Andy Miller affair. In all three cases, I feel there are significant questions being left out. Firstly in the Stockwell investigation there were other personnel involved, for example the surveillance log was not individually filled in by Ian Blair? Although there were significant errors in the police strategy what does one expect in the aftermath of an incident which caused a high level security alert and thrust upon the police the responsibility to react quickly so as to protect and keep safe the nation in such perilous times, the men were shaken and so were we even weeks after the incident? Secondly can the police force be said to really have ridden itself of all discriminatory methods? Were there other reasons as to why Blair chose not to pick him, have those been identified? Also, in terms of the Miller case, there were other members of the committee who contributed to the decision; although Blair may have been persuasive he did not make the decision alone. The whole affair points really to the system. If he is found to be wrong on all three charges then we have to question how one man can be allowed to kill a man, discriminate against another and fuel such high levels of corruption. If he is found innocent, then we have to question how a system could allow for such grave blunders and is still allowed to continue smoothly.
