I've seen those article about TSA missing stuff, both from ordinary people and from the "testers". I have wondered if part of it is how hard they get pushed to go through so many passegers.
The latest "news", however, is that they now have service dogs that can ID someone with Covid. It is ironic that they are using them on the airport workers (including TSA workers), first. The article seemed a little uncertain - or maybe the Gov't is uncertain - when they will include passengers. It must take some time to train the dogs. What do they do, take them to the ICU? They supposedly smell the affects of body changes, like the changed smell sweat gives off when you have Covid. Sounds like they can catch an "a-symptomatic" Covid patient. We already have the bomb/gunpowder & pot sniffers. Did you ever want to know what the dogs are saying about that when lying around and talking over a beer?
And what happens when they indicate a positive? Do the people in those full decontamination suits swarm whoever it is?
As long as they don't have them for full diapers....
We shouldn't be surprised. Dogs, depending on breed & individual, have between 20,000 to 50,000 times better sense of smell than we do. I think it is 50 more kinds of sensors than we have.
While we are sequestered at home, here's something to do. The best book I know about, very readable, is Alexandra Horowitz's "Being a Dog: Following the Dog Into a World of Smell".
Also, try Cat Warren's "What a Dog Knows".
