Can't happen to my boys in their school. It's upstairs.
I've had my kids in public school and homeschooled. I now am sending my oldest grandson to private school. To me, it's what works best for you and your kids. IMO it's not what happens at any of these but about what the parents allow. Homeschool and private school kids can still get access to this stuff from friends, tv, webb sites etc. Parents must be parents.
