It is Legally Named a "DePredation" Shoot for a reason. Only failure here was that You were off the Mark. Should have killed it. Were You using a Semi-Automatic? That is what is best for Defending the Flock. Get in some Target Practice. Then, as Noted above, next time - SSS (Shoot, Shovel, and Shut-Up)! Your Brother will, or will not, get over His Failure as a DogFather. It is HIS Problem. Spend No More Mental Energy Worrying about "Water Under The Bridge" - Live Well.
