Public school officials, like state legislators, have a responsibility to
protect students from sexual assault, particularly at the hands of teachers or
other state employees. In fact, it is hard to imagine a higher interest than
protecting students from sexual predators. Yet, the constitution mandates that
any law, regardless of the interest it seeks to protect, meet certain criteria.
Among these criteria is the requirement that laws not be “substantially
overbroad” or unconstitutionally “vague.”
