I think the operative word is advice. That is, I think that having a preamble of some sort, having some standards against which we try to interpret the meaning of the act--and the act is going to be interpreted over and over again in the event that it passes--is terribly helpful in trying to sort out the differences between situations that appear the same but are in a context that in fact makes them different. It's impossible to imagine all the rules one could ever need in administering any kind of code that relates either to conflict of interest or ethical matters in which value systems obviously differ. I think it would be helpful.
As I say, I've no particular preference for the ones we have. They've turned out to be useful in some respects, but others could easily be developed. I don't want to make that argument. I'm just arguing that something would be helpful.
