Bruce Schneier on TSA and airport security:
The humiliation, the dehumanisation and the privacy violations are also harms. That Mr Hawley dismisses these as mere “costs in convenience” demonstrates how out-of-touch the TSA is from the people it claims to be protecting. Additionally, there’s actual physical harm: the radiation from full-body scanners still not publicly tested for safety; and the mental harm suffered by both abuse survivors and children: the things screeners tell them as they touch their bodies are uncomfortably similar to what child molesters say.
The current TSA measures create an even greater harm: loss of liberty. Airports are effectively rights-free zones. Security officers have enormous power over you as a passenger. You have limited rights to refuse a search. Your possessions can be confiscated. You cannot make jokes, or wear clothing, that airport security does not approve of. You cannot travel anonymously. (Remember when we would mock Soviet-style “show me your papers” societies? That we’ve become inured to the very practice is a harm.) And if you’re on a certain secret list, you cannot fly, and you enter a Kafkaesque world where you cannot face your accuser, protest your innocence, clear your name, or even get confirmation from the government that someone, somewhere, has judged you guilty. These police powers would be illegal anywhere but in an airport, and we are all harmed—individually and collectively—by their existence.
