Because no one except the Nazis and their victims knew about them. They were top secret except to those who were either running them or in them.

they were by no means secret. Given the civil disorder in the early 1930's and the effect they appeared to have in restoring order, they were not seen as a bad thing. Though they were announced as a temporary measure, the main ones never closed and evolved into far crueler places during the war and into the Holocaust. By the time Jews were sent to the camps, the war had started and information coming out of occupied Europe was more problematic.
Also note that the concentration camps were different from the extermination camps.
It was considered that the best way to stop the camps was to produce a military victory and an unconditional surrender.
The Allies (including Britain) stopped the Nazi concentration camps and the Holocaust by invading and defeating Nazi Germany.
Allied troops overran Nazi positions in 1945 and liberated the camps through direct military force.
well yes and no.Concentration camps stopped before Hitler died, 2 prisoners escaped from Aushcwitz and told the Jewish citizens about the camps.
These things didn't figure anywhere in most Germans' priorities at the time.
There many things that used to stop people escaping from the camps. The camps were heavily guarded and most people feared for their lives and thus chose to stay in the camps.
there was nothing wrong or illegal about concentration camps. It was what people in them did that was wrong.
There was no 'international policeman' to stop them.
The Allies (including Britain) stopped the Nazi concentration camps and the Holocaust by invading and defeating Nazi Germany.
when Germany surrendered to the allies
the people running the camps ran away or surrendered
Allied troops overran Nazi positions in 1945 and liberated the camps through direct military force.
The concentration camps were an invention of the Third Reich as a place to send anyone who they considered inferior or dangerous to the Reich. Once Germany was defeated, the concentration camp system came to an end. The few survivors went to resettlement camps, and eventually picked up the threads of their lives from there.
many people thought it was to horrific to be true
well yes and no.Concentration camps stopped before Hitler died, 2 prisoners escaped from Aushcwitz and told the Jewish citizens about the camps.
nothing can be done
No one, concentration camps were never and have never been stopped. This may be a reference to Schindler, he employed Jews in his factory, but it did not keep them out of a concentration camp, when the ghetto was cleared, they went to the concentration camp with everyone else, to walk to the factory to work every day.
