TSA: Fail
The entire TSA paradigm is flawed. It requires an impossibility for it to succeed. For the TSA model to work, every single possible means of causing danger to an aircraft or its passengers must be eliminated. This is an impossibility. While passengers are being frisked and digitally strip-searched a few dozen yards away, cooks and dish washers at the local concourse “Chili’s” are using and cleaning butcher knives.
