You touched on the extra privacy implications related to combinations of data sets and gave an example. How do you possibly put in place a policy that deals with the possibilitiy of personal information being disclosed when different data sets are being disclosed across the breadth of government? How would you know how one department's data would affect things in combination somewhere else, and how do you put a system in place that would challenge people to make those kinds of considerations?
