Scylax - Alan Turing will not be elligible for a posthumous kinighthood becuase he died a convicted criminal.
As the majority of people have confirmed on here - you cannot turn a blind eye to a crime on the basis of the perceived wonderfulness of the criminal - that is to make a mockery of the law.
The thread of civilisation that the law brings to modern society is the willingness of citizens to leave it untouched, and to start messing around with it on this basis leads to an endless list of similar pleas for other more or less deserving causes.
If we start, where do we stop? Do we pardon the Krays because they loved their mum and did their bit for charity?
The only fair way to apply the law is the way it applied now, without fear or favour, and regardless of the contribution of Mr Turing, he as convicted of a crime which he commited at the time when his 'crime' was against the law.
That does not change - nor should it change, because to do so weakens the pirnciples and practices of law, which is a dnagerous slippery slope.
I entirely agree with Jack's point - let the more enlightened times we live in enlighten people who think differently - that is the legacy which AT would probably have wanted to see in his name.
