Bizarre? 20 kids get massacred in a school - but never mind - cos now you can get a bullet-proof backpack to keep the little tykes safe. Er, well not the 20 that just got killed of course, and it only works with backshooters; oh, and you have to be wearing it at the time, and . . . . . well, who cares, if we can make a few bucks out of peoples' fear?
