“Who stripped her?”
She was forced to strip by those in authority over her. Try that in a work environment and see what happens to you.
Thank you for your sourceless assertion.
From the actual decision:
The search of Redding’s person was conducted by two employees who were of the same gender as Redding, and the search took place in the privacy of the school nurse’s office with the door securely locked...Redding was not physically touched in any way during the search, and she was not asked to remove her bra or underwear.
