Best objection to The Gestapo was a cruel police force that was the cause behind the atrocities towards Jews?

For a research paper on the Gestapo my thesis statement is "The Gestapo was a cruel police force that was the cause behind the atrocities towards the Jews." One part of our paper has to be the best objection, or the opposite view point of our thesis. I can't think of an objection to my thesis.
