I understand. The nuisance alarms, which we're familiar with, are where you do detect very small amounts of drugs, and they're actually there, but the person is not carrying a significant quantity. We recognize this problem. For example, we don't swab currency, because the drug trade is largely a cash business. We don't swab currency.
I think it's a question of what the result is. If we detect a tiny amount of drugs through an ion scan, then that just leads us to examine further. It's not an indication of guilt.
