The American Journal of Forensic Medicine and Pathology figures out what some of us have known all along: you can’t get rid of everything on airplanes that can possibly be used as a weapon.
(They stabbed a few dead pigs with various everyday items, such as pens and broken glasses. Shockingly, all of them can inflict lethal wounds.)
Your weapon is that squishy grey mass between your ears—everything else is just a tool. I know people who are more dangerous with a paperclip and a hand towel than your average soft suburbanite would be with a loaded machine gun. You can kill someone with a freakin’ paperback, if you have the attitude and the will. Trying to make society safe by taking away all the sharp, shooty, or pointy things is a fool’s errand.
