Having gone through police training in another life, you are absolutely correct. I think it's deeper than just what you wear, it's the attitude of the higher ups and overall culture. The leadership team for police that wants you dressing all paramilitary and in all black is going to have a focus on you acting a different way during training and in what your day to day is like than the other group.
