Is this the troubling trend that won't go away?

Police arrested two South Carolina middle school students last week for having sex at their school at least three times over the past month, reports WYFF. Investigators said that both 12-year-old students had asked to go to the restroom on Friday, and when an unusually long time had passed, a teacher went to check on them and said they were found involved in a sex act in the boys' restroom. Our national Mom•Logic survey found that one in five kids has witnessed sex at school. Check out our exclusive Sex in Schools Momvestigation here. Has your child witnessed sex in school?
