I don't know that you can be sure. I think one of the problems with trying to put too much in the code is that it gives us the false impression that you can cover off everything, and you can't. There are going to be times when people accuse people of wrongdoing and it's entirely invented to create some sort of political storm, and there are obvious political reasons for doing that.
I would also say that when it comes to what the public actually takes in and what they do with this kind of information, if a voter gets their political information from a newspaper, and they read about a scandal, and they read about the economy, and they read about health care, and they read about all these different types of things, at the end of the day, the voter has one vote in an election. Whether or not somebody disclosed their information on time or whether or not there was an apparent conflict of interest is only one factor that may or may not affect the decision they make. When it comes to actual accountability for these things, that's the system we're in.
