"I'm sorry for what we did to Turing". On the other hand, if you don't happen to be a genius, tough! The countless, ordinary blokes in the street who happened to be homosexuals and were prosecuted in the 1950s and earlier can go hang as with the millions of others who with hindsight suffered unfairly at the hands of various laws of the land in past centuries.

However it seems to me that for people alive today to apologize for laws made by people now dead is a cheap, meaningless (reform laws on gay sex were passed long ago - that's an 'apology' that means something) gesture. I'm all for memorials and public honourings of people like Turing (I read the Hodges biography a long time ago and was greatly moved) but I wish people would stop cheapening the word 'apology'.
