I quite like the 'apology' he received from the conference organizers:
> In July 2013 I told the NSA-affiliated conference organizers that I was having some problems in getting my visa, and gently asked whether they could do something about it. Always eager to help, the NSA people leaped into action, and immediately sent me a short email written with a lot of tact:
> “The trouble you are having is regrettable… Sorry you won’t be able to come to our conference. We have submitted our program and did not include you on it.”
