Some interesting points made. As an ex-nurse of some 37 years experience, I have witnessed, I suppose several hundred people die in the course of my career. Every one that I remember slipped away peacefully. Some were gone in a matter of moments. Regarding McVeigh - an injection will allow him to fall peacefully asleep. Several science fiction stories over the years had an interesting concept. The killer was made to experience time and time again the last moments of the victim. I suppose that concept is in the realms of fantasy, but just imagine if some of the billions spent on arms were turned to that type of research.
