One thing is clear IMO: it is profoundly irresponsible for a politician or other public figure to threaten or criticize a pilot for exercising professional judgement in conducting a safe operation, as the Polish PM did in 2008. It is also extremely foolish, as his family and friends perhaps now understand when they are honest with themselves. Not to mention the family and friends of the other dead. I daresay a very bitter lesson has been learned about the need to comply with procedures - pretty sad.
I dare to say that even this is is not clear. The flight to Georgia took place almost two years ago.
Since then the President flew dozens of times (likely - in different weather conditions) without incidents. Since then - I'm sure - both sides (the President and the pilots) learned from that lesson.
