But the whole point about corruption is that it doesn’t respect the rules, be they codified or cultural. By having a fixation on a document, the bigger picture gets missed.
I suppose I think (in practice) the law reflects the opinions of those in power and you’re suggesting those in power reflect the law. The problem with your position is that it’s demonstrably not true - the powerful do what they want almost regardless of the law. I suggest a pragmatic position which holds that the best legal position should be sought all the time should be the way things work. I just don’t see how that can occur when you have a rigid document written, in the most part, hundreds of years ago.
