Guess the moral of that story could be, "Don't live in West Virginia." On duty LEO, returns fire after being hit himself, and the court sides with the guy who shot him? I have to wonder if the perpetrator was charged with anything? Something doesn't smell right, and google isn't bringing up anything that looks remotely similar.
Was he using reloads? Or was he using factory-loaded duty ammunition?
Really, if stories like this become urban legends, creating even a semblance of hesitation or doubt in a gunowner's mind as to whether to defend themselves with a legal firearm, then the left has already won. Next, we'll be getting sued for "cruelty to animals" when hunting. Who needs the Second Amendment?
