auschwitz

"People should look at this place and think about our moral responsibility," says Pawel Sawicki, a longtime guide at the Auschwitz museum in Poland.

Vladimir Munk left Auschwitz 75 years ago after the concentration camp was liberated by Soviet soldiers. Now, for the first time, he's going back to a place he calls a burial ground for his family.

Survivors and victims' descendants traveled from around the world to the Nazi death camp, at a time when Polish politicians are pushing controversial Holocaust legislation.
