brilliant move- both seriously and sarcastically speaking.

as i have always trained my front line banking staff, a uniform doesn't mean squat and the i/d needs to be "looked at"

now as to your question, the tsa will take a page out of the "tootsie-pop playbook "......the answer is 3.

i/d #1: shows who you are
i/d #2: show that the i/d used to i/d yourself is in fact valid and one
i/d #3: simply has the word baaaaaaaahhhhhhhhhhhh on it*


*if you do not have i/d #3, you will now be allowed to fly
