Reasons to be fearful, part 1

Following the dreadful school massacre in the USA last week I spotted this story today. I guess it's inevitable but still seems catastrophically stupid to me, an 11 year old has brought a gun to school for "protection". I can just imagine playground disputes over sweets, marbles and kiss-chase being resolved via a Glock 9mm and a clip of soft nosed rounds, what the hell kind of society are they trying to create over there?
