Students in select areas of the country are heading back to school with the likes of bulletproof backpacks and whiteboards that also work as shields — even though some are calling it overkill.

“It may be well-intended but it’s not well thought-out,” said Ken Trump, a Cleveland-based school safety consultant who is also the father of young children, on NBC. “I would ask this question: If you need a bulletproof backpack, wouldn’t the child also need a bulletproof front pack and a helmet and a Captain America shield?”

But many parents and school administrators aren’t taking any chances in the face of the Sandy Hook, Conn., massacre and, the latest, this week’s gunfire scare at a Decatur, Ga., school. Meanwhile, makers of the school-age defense items say business is booming.
