If we raise the threshold for obtaining information, you're telling us that we're depriving you of the ability to continue the investigation to be certain, because you can never really be certain. Even when you invoke reasonable grounds to believe, we agree that you're not completely sure.
On the other hand, if you use the lowest threshold, what does that allow you to do that you couldn't otherwise?
My other question concerns the potential for abuse of this standard—this lower threshold. There may be risks involved in misusing it to obtain additional information. I have concerns about this.
