I've watched The pianist (movie) a couple of days ago, and wondered about the reality of some scenes. In the movie, there is alot of open violence agains the Jews, including shooting random "prisoners" (slave workers?). on public streets, alot of other forms of physical violence, bodies on the streets, etc, in a relatively peaceful period (alteast in Warsaw, no actual 'war' activities happening there at the time)

I didn't have the best history teachers in school, but I was always under the impression that the germans did most of those things privately/secretly (atleast in germany). More in the style of "everything will be ok, we will just move them somewhere else, they will live peacefully there, they'll work, get paid, etc etc.", and then ship the jews on trains to eg. Auschwitz, and we all know what actually happened there. I was thought that alot of the germans had no idea what actually happened there, and thought that the jews will actually be okay (stay alive, work,...), and didn't protest the actions of their government. I was also tought that alot of people just dissapeared (noone knows when or where, but not in a public-street shooting style). Or was this only for germany, and the germans didn't care alot about their public image in other countries?

So, was there actually alot of movie-style violence at the time, or was this an exaggeration, and most of the violence happened "hidden" to the public eye?
