Just watched the talk show „Markus Lanz“, the first 50 min was a discussion about Ein Jahr „Wir schaffen das“.
Boris Palmer, the mayor of Tübingen, took part in the discussion.
For people who are fluent in German worth to watch in the ZDF mediathek (not yet available, I will later post the link below in the comments).
Jochen Busse (actor and political „Kabarettist“) and Michael Spreng, journalist and former „Bild am Sonntag“ head discussed with him.
