All for show, and speculation, a secret meeting on the Tarmac, what, they do not have phones or secure e-mail? HAHAHA, I work right by the airport, all for show..
Remember both ex-prez clinton and the current AG have protection details. The meeting also took place with a controlled space - airport property. This meeting was planned.
And even if clinton would have been so bold to have thought he could just jump on her plane, The AG's protection detail would have needed to clear it first.
Both of their movements are very controlled.
