Fashion is getting dangerous. The whole trend of spikes is dangerous. Sure, nothing is actually pointy enough to harm someone, but in my mind, I imagine some kind of fashion ninja whipping off a shoe or earring to be used as a weapon should a threat arise. To my knowledge, you're still allowed to go through the airport with spiky jewellery. Isn't it kind of funny how you can walk through an airport armed with spikes, but you'll get searched and barraged for trying to smuggle in toothpaste?
