They don't already have some form of content filtering in place to protect kids in schools?
You'd think... Also, there was a funny thing from about a decade ago where they spent something like 100M developing a filter, and at the public release, it took a 12 year old 10 minutes to circumvent :D
Well yeah kids are always going to find a way around, but we have federal laws that require us to at least try. We can actually lose our funding if we don't have something in place.
