Kaczorowski was a president of Poland, retired, but when he died he was performing very special representative duties.
I am sure you all know the history(?):
the official and legal government of Poland during WWII in London requested Red Cross investigation after graves of Polish officers
were discovered in Katyn in 1943. Stalin used this as a pretext to break up formal relations with this government and forced
governments of GB and the US to follow later. The pretext was that the officers were murdered by Germans which was a lie known
almost immediately in the West. Then Stalin installed puppet communist government in Poland and again US and GB gave it its
recognition and legitimacy.
During Soviet occupation of Poland, the London government was the real government of Poland for Polish people, except of course
the communist thugs that learned Polish and were running the puppet government.
Therefore President Kaczorowski was a very important figure and should be buried in Wawel. Actually the room where President Kaczynski
is buried should be converted to 'Smolensk room' and all victims of Smolensk murder should be buried there. It will happen.
