Backpack shield

I thought this (Backpack shield) was pretty depressing, not because some parents may and this company feels there's a need for it per se, but because of the thought they might be right.

"Stronger than a sewn in level II liner, the BACKPACKSHIELD tm is N.I.J. Level IIIA & stops hardened higher velocity 9 mm Full Metal Jacket (copper) and 44 Magnum (SWC) rounds flat in their tracks. The patented DupontTM Kevlar® multilayer ballistic composite BACKPACKSHIELD tm weighs less than a text book, measures 17" high by 12 " wide, is less than 1/2" thick, and fits inside 1000's of standard size (High School & Collegiate) backpacks. It's available in a variety of school colors, optional personalized photo (i.e. favorite athlete, pet, team, mascot etc.)"

I'm not advocating either way for or against armoring children with Kevlar, but I think it's more a matter of when, not if, there's going to be another school shooting. Wangos. There has to be a better way to protect school children.
