If you fail to kill an intruder because your sights are off 2-3 inches, its not the zero issue.

If we are talking hostage or head shot only, totally different and I"m expecting anyone doing this is going to know their zero exactly as its not so much a heat of the moment shot but a precision shot.

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
