Q. Defences the Milwaukee County Juvenile Detention Center established a new policy which required each unit of the facility to be staffed at all times by at least one officer of the same gender at the detainees housed at a unit. The purpose of the policy, administrators said, was to reduce the likelihood of sexual abuse of juveniles by officers of the other gender. Because there were many more male units in the center than female units, the policy had the effect of reducing the number of shifts of men. Two female officers sued for gender discrimination. The district court held for the county, find outing which the policy of assignment was based on a bona fide occupational qualification (BFOQ) and so was not illegal gender discrimination. The officers appealed. Illustrate what would be evidence which the county had a valid BFOQ?
