One of the funniest quotes here is:
Some doctors, patient advocacy groups and medical-equipment suppliers created their own notification cards and letters long before the TSA's new stricter security screening rules and enhanced pat-downs went into effect. But Linda Aukett of United Ostomy Associations of America said: “Some TSOs (transportation screening officers) responded with ‘Don’t bother showing me that paper. Everyone has a printer. You could have forged that letter.’ So that had a lot to do with the TSA coming up with its own card.”What forgery is the TSO concerned about? It's just a note to privately explain a medical condition!
And, as one of the commenters on this article said:
If the screener cannot understand the spoken words, why do you think he/she could understand the written ones.I can't see how these ridiculous cards seem like a good idea to anyone.
