Does anyone suppose that a uniform or some emblem of rank or even of social class guarantees the absence of such misconduct.....because if you do you are grossly misinformed and have no grasp of history or reality.
As to whether it is becoming more of a problem or to what extent it is can be argued but to suggest in one's time it did not happen is pure folly.
The key ingredient is whether the victim considered the conduct to be offensive is the moral standard and whether it violated a Law or Regulation is the legal standard.
