Comment: If a dude is actively threatening to kill someone, a head shot with a scoped .308 or .223 may be reasonable.  The same is not true of a dude sitting alone in his house.  In the latter case, there is no active threat.  We people instruct police to kill the dude anyway just to prove that they must do what we want when we want it.  Okay, if that is the kind of society we want, so be it.  Recall, that we really know nothing about what the dude did, but I guess the point is that we should kill him to teach others to do what police officers tell them regardless of the circumstance.  Okay, whatever.  We craft the society in our image and reap the benefit when citizens kill because we have taught them how little value life has.
