Not a PZPR member? Known for his family's AK background?
Clearly neither the lack of Party membership nor the father's former allegiance were a problem, given that both those factors were equally true for The Dear Leader Chairman Kaczynski, and his application to be allowed to prosecute dissidents during the commie era was accepted.
But then the supposed former allegiance of Daddy Kaczynski was no problem to him getting back into university, no problem for him being allowed to teach the children of the elite, no problem for him to be allowed to work in the American embassy, no problem for him to get a nice flat, no problem for his kids to be movie stars, no problem for him to be given a multi-million zloty villa in Zoliborz. Although of course there is a very obvious reason why an AK officer got that while AK enlisted men were being tortured.
You are still repeating the lie thast he volunteered "TO PROSECUTE DISSIDENTS".
He volunteered to prosecute criminals at a time when distributing unauthorised newspapers was a crime, a crime one of his fellow senior figures in the PiSlamic State actually prosecuted charges of.
