I believe the issue with the alarm is that most people don't repeatedly flag the same alarm. E.g. if a given test were to generate a false positive, you would expect that it wouldn't generate a false positive the next time if run on the same article, especially if the machine correctly doesn't alert on other innocuous articles. So in the normal situation someone sets of the chemical detector, once , gets pulled aside…
> if a given test were to generate a false positive, you would expect that it wouldn't generate a false positive the next time if run on the same article I don't think that's true. Remember that the test doesn't actually detect bombs. It detects certain chemicals. Now, sometimes it might just randomly report a false positive and then you'd expect it not to trigger the second time. But some of the chemicals it is buil…
From what I am hearing from others, normally people barely even get that much special treatment after a non-transient false positive. Agents suggesting "Maybe it was 'Innocuous Product X'" so the passenger can say "Yup, that is probably it" seems to be common, but not the sort of treatment they are going to give to people that they have a bias against.
