In both the US and UK, the safety of kids both on and off school campuses is a high priority, and rightly so. Now Massachusetts-based MJ Safety Solutions is offering a special backpack containing a bullet- and edged-weapon-resistant panel, certified as a NIJ Level II plate which can withstand medium and low caliber rounds. Adding 20 ounces in weight to the regular backpack, it will provide either back or front protection - but of course has to be held or worn in the appropriate place. I suppose if you had $350 to spare, and didn't mind looking like an idiot, you could wear two. MJ Safety claims that, of the 328 shootings in the US since Columbine in 1999, 97% could have been prevented by using their bags.
