I would imagine, like many places, that discharging a firearm in the city limits is illegal, while shooting a bow and arrow is not. If this subdivision is outside the city limits where discharging a firearm is legal, then while perhaps irresponsible, it wouldn't be illegal.
My question for you is do you know what precautions were or weren't taken here, or are you just assuming he flung an arrow into the direction of his neighbors house? From that video, I cannot determine whether he is shooting that arrow into an open field or wooded area in the distance anymore than I can determine that he is shooting it directly into the front door of a house across the street. The point is, you are making quite a number of assumptions based on roughly a 60° view of a 360° picture.
