“It keeps happening.”
This is why when I hear about a cop getting shot, I really could care less... Live by the sword, die by the sword.
Let's say there is a homeowner who believes in carrying a firearm on his person, and he believes in using deadly force to protect himself and his property. Suddenly he is confronted by an armed burglar. The homeowner draws his pistol and fires, missing the suspect. The suspect returns fire, killing the homeowner. By your creed, "you really could care less" because: "Live by the sword, die by the sword."
