No. Perhaps the only thing I could suggest is the difference in thresholds. Maybe we didn't fully explain this. In order for there to be what we consider a positive hit to trigger the threat risk assessment process, somebody has to meet the threshold. In other words, we don't record anything below the threshold.
On fentanyl, for instance, you may hit 25—and don't ask me about nanograms, because I'm not the technical person. You might hit 25, where the threshold is 100. We don't record that. That is something that the ion scanner did detect. Whether or not that's a reference to that, frankly, I'm purely speculating.
