You REALLY think two "old friends" would hold up traffic at a busy airport to talk secretly on the tarmac for a half-hour about their GRANDCHILDREN???

Please......but you are right.  It is speculation.

Evidence.  Yes.  I am the one here who calls for evidence before issuing condemnations and accusations.  And I am not issuing any accusations.  However - the evidence is there that there is an appearance of impropriety.  The questionable actions occurred during a highly sensitive investigation into Hillary.  These are allegedly two brilliant attorneys - they couldn't SEE the the problem with such a meeting?
