Our JV girls basketball coach was caught doing that. He was suspended during the investigation, which began because a female student complained, and then he was fired when the investigation revealed that he had indeed sent sexually explicit messages to female students who were under the age of 18. He went out of town for a few months, moved back, and the next year was arrested for having drilled a peep hole into a female neighbor’s apartment. He is now in jail.
We don’t know yet whether this assistant principal has actually done anything inappropriate. Once the investigation is concluded, if he has been shown to have sent “improper text messages” as defined by the school board, he would most likely be fired.
Would you want someone who crossed the line of propriety with your female child to remain in a teaching position? OTOH, would you want to sentence someone without a trial of his peers?
