"further investigation" meaning you get your testicles rubbed by a TSA clerk in the private room. For having used hand soap.

You are being a stickler for semantic purity without gaining anything from it. Some of us have used the term "bad results" yielded by poor testing methods. Regardless, if a test alarms on commonly used products, it is for all intents and purposes a false alarm or false positive and the shorthand is useful. If the methods used are sensitive to compounds used in explosives but also used in a wide variety of products, the test cannot reasonably be used to justify TSA's genital and anal massages of innocent passengers in the private rooms. After two years, you have all these alarms leading to no discoveries of explosives: it is probably a clue for you folks to try something different.


Like hand soap, shampoo, or any of the other household items that contain these chemicals. After two years, that's all you've found. What exactly is dangerous about these? Oh, they could be used in a bomb...

Only if you accept that since terrorists both reason and breathe, all reasoning and breathing beings should have their privates investigated. That's the kind of test you have. One too broad to be either useful or decently used on innocent human beings.

We are fortunate that our TSA clerks have the education and work background in chemistry and test methodology to set us all straight.
