Seems to me the lesson here is not, what really happened, but what is the impression your story will leave of you at the interview.
Judging from the reaction here, I'd probably come up with something more than "I did just one thing wrong and I was fired"
On a side note, it sounds like TSA has some training issues... Not sure what to say about that, but maybe you had a valuable lesson about not allowing the training department to drive the quality of your training... You gotta get in there and be proactive about your progress and stay WAY ahead of where you think you should be. Your standards need to be higher than the training department.
And, sometimes training departments do SUCK... But they'll never tell you this, and you might not figure it out until it is way too late... Sometimes they can't teach, sometimes they are personally frustrated, sometimes they just know how to Test, not Train... So just don't expect to be well "trained" at the regional level, and don't beat yourself up.
