Our concern would be that the inclusion of incidental information will in fact lead to what others have described as “mass surveillance” and collection of too much information. Concerns have also been raised about metadata not being properly defined and included. By combining that with incidental information...which often could be very important information. Incidental doesn't mean it's just minor information about somebody, but that something is collected outside of the scope of what the targeted investigation is. In that respect, we don't have a clear idea of what that incidental information would be. If it is to be retained, it would have to meet the same authorizations and thresholds for collection and retention and querying. As Ms. Tribe mentioned, we already have concerns about whether those thresholds are at the appropriate level to ensure adequate oversight and adequate sorting of that information.
