Formal complaints--and again, if I'm misspeaking here, I'll write and correct the record--I believe are in the 600 to 700 range per year, and that's on 95 million transactions. There's a range of other informal ones that wouldn't be in that count. So the total number is probably higher.
We see complaints that are serious, and we look into them and we mediate them. There are others, quite frankly, where an allegation has been made, and it's the view of the border officer that the event did not unfold that way, and we simply have no way of corroborating one way or another. But we take all of them very seriously, and many of them, as I say, are referred for internal investigation.
