However, because the crazy and ignorant believe something does not mean its necessarily wrong. There was the whole odd bullet/no bullet/bullet thing. I've wondered about using lasers as weapons as long range assassination tools; they're heavy and ridiculously expensive but the beam goes a long way. You couldn't kill somebody from orbit (well you could but refraction and beam spread would mean you also inevitably vaporized everything nearby) but ten miles would be no problem.

All lasers make ionization plumes when they reach the target even if the beam is something invisible like infrared. In other words Bhutto's head should have shot brightly colored neon-hued plasma as her skull vaporizes.
