A gun is an interesting weapon; it can be hired, of course, and naturally doesn't care who hires it. Something much the same can be said of the gunman, too.... In the far future it may become extremely difficult to even think of doing violence on another creature, much less actually performing a violent act on a fellow human. But some people will still wish to do nasty things to others especially those whom they think really deserve to be uh.....removed. And so reaching back into the past for a less squeamish individual seems the perfect solution. Except of course when it isn't.
