Detecting Killers While we justifiably spend a lot of recourses at airports trying to stop an invisible threat, a more observable killer continues to thrive. The killer we can normally observe and terrified to smell or touch, drugs. If we've learned anything about terrorism, it's the unfortunate truth that terrorists come in all shapes and sizes making them extremely difficult to stop. Likewise, as we've learned lately so can the drugs. As we continue trying to detect all killers at airports, a major observable societal problem continues to reveal itself and increasingly spread around the country. We're asking a lot from TSA considering an airport is filled with so many people from all over the world. Given the nature of what an airport is and the state of the world, I'm honestly surprised to see airports operating at all. After visiting many of our streets in America, I can't find the words to express my disgust of this seemingly ignored tragedy.
