We sincerely regret and apologize for the experience Mrs. Dorn had at JFK. The Federal Security Director for JFK has personally reached out to learn more about what happened so he can help ensure that she and others will have better travel experiences in the future. While security is our primary mission, he apologized to Mrs. Dorn for not delivering the customer respect he wants all passengers flying through JFK to experience and offered to meet her the next time she flies through this airport.

As apologies go ... I'll give this one a 9 out of 10. (Of course, this should've never happened in the first place, but that's why the apology was needed.)
