This is possibly why Turing isn't pardoned - it'll open the doors for all the (living) homosexuals who were convicted to make compensation claims.
The question, now, is whether to posthumously pardon the others.
Update: Found an article. Turns out they haven't been pardoned, but their convictions are now "disregarded" and no longer appear on their criminal record[1].

It would be good if they went further and pardoned people.
