  oooh that’s a tough one. Part of me would want to be honest (and to get published) so yes! but then maybe it would be better for everyone to just destroy the weapon 😕
  
  In reality though, I don’t think I’ll be doing anything so exciting any time soon, as most of my research is about helping or protecting biology, I doubt I’ll stumble upon anything like that!
