Bulletproof Backpacks for school children

Have you guys seen on the Daily show almost a year ago that a person wanted to get bullet-proof BOOK COVERS. It was pretty fun with jason jones reporting it. I dont remeber the persons name, but he said they can hold it up as a shield to cover their faces and throw it as a weapon. ( he was VERY serious about this! lol) So at the end, Jason Jones took a book and a guy was shooting him with a paintball gun and he had to use a book as cover! Im afraid thats a bad idea by the outcome lol
