Guy I know's story:
He grew up in one of the racist carolinas. When in his early 20's, he came home and found that the neighbor's dog bit his niece. He went outside to confront the neighbor(who's dog was right next to him). A near fight occurred. Toward the end of said near fight, the guy I know turned to his house and yelled for his wife until she came to the door. He then yelled for her to go get his gun. Once his wife "fetched" his gun, he started to raise toward the dog. This guy said that his neighbor suddenly relaxed and joked, "you can't shoot my..." BANG!(bang was yelled really loud by the guy I know at this point of the story). So he killed the dog. The neighbor took the dog and buried it in his back yard. Then the guy I know called the police and reported the bite. Animal control then came out to get the dog(evidently they need the head of the animal to test for rabies). Upon finding that the dog was buried, they made the neighbor dig the dog back up so they could take it away.
Please note that I had to translate all of that from Red Neck to English so I may have lost something in the translation, but I am pretty sure that was the gist of it.
