Making the execution a private affair, and hanging the method, that is. Sends the wrong message. Should have been a beheading with the severed head stuck on a pike in a public square and left for the vultures to dispatch, all of it televised to the entire Arab Islamist world. It's what they understand best. No, make that: it's the only thing they understand. The private hanging just reinforces their conviction that we're pussies; old women against whom they can with absolute assurance achieve ultimate victory if they just stay the course.
