In the interests of time, I think the Maher Arar report is directly on the point of how we decide which information to exchange about.
Now, keep in mind that entry and exit information will predominantly be information about people who already have a right to live in Canada—Canadian citizens and permanent residents. The Arar report was a good example. I think we should only be tracking people where we really have some grounds to suspect there's actually some sort of issue. Otherwise, it's a tremendous public expenditure with enormous risks, which is not justified, in my mind.
