Whoa, Andy! You are raising a lot of topics in this question.
I will just mention one topic. I would like to see the Scottish Parliament exercise indepence on the specific question of rendition - the use of its airports to illegally take indivuals to places where they can be tortured. If Westminster wants to pretend it's OK, I'd like Holyrood to speak out for Scots opposition to inhumanity, which I feel is real.
I know the questions you raise are far more economically based and I know others will have strong opinions! Good luck- I look forward to seeing some.
