I don't know how it is in Virginia, but in Texas, administrators and any one else must report even a suspicion of inappropriate behavior with a minor. If you fail to do this, you will lose your certification. At that point it would be investigated to find out if the charges are legitimate. The offender would immediately be removed from the school until the investigation is complete irregardless of guilt or innocence. Just a few weeks ago a Texas coach was removed from the school because of allegations of sexual assault against a minor that occurred in a county 40 miles away. If Virginia's laws are similar, the person may know before an arrest is made.
