I agree. The “news” item is likely just a fluff piece; it begins in dramatic storytelling fashion.
As is typical, the story they tell is dramatic, but questionable. The victim brandishes a weapon, the burglar runs off, AND THE GUY CHASES THE BURGLAR OUTSIDE HIS HOUSE, holding him at gunpoint after the thief stumbles and falls.
Use of a firearm like this is illegal in many states. Many states have an “imminent fear” clause governing when use of a firearm is legal. In my state, you can't use a gun on a burglar if he runs away. If the guy had plugged him in the bedroom, that would be OK, but as soon as the burglar ceased to be an immediate threat, the home owner can't even brandish his weapon.
