Thick line
The thick line policy was the term used by prime minister of Poland, Tadeusz Mazowiecki, in his first parliamentary speech in Sejm, in 1989.
He said, "We split away the history of our recent past with a thick line. We will be responsible only for what we have done to help extract Poland from her current predicament, from now on".
In more recent years, his intentions were considered by many people, and his gruba kreska is often understood as a policy of nonpunishment for crimes committed by the communist regime of pre-1989 Poland.
