He shot him in the driveway as the father was leaving. You would do that? That’s murder.
Pushing Grandpa? Near the pacemaker? How calculating and utterly staged.
No doors kicked in, no marks on Grandpa,no broken furnishings, no weapon on Brice.
No need to shoot the man.
Re-read the story. The grandfather was escorting him off the property when he turned and attacked. I'd have shot the bastard, too.
Darwinism at work here. The dad knew grandpa had the gun and continued to be aggressive and pushes the old man again in the driveway even after knowing he has a gun. The gene pool is better off without this foolish man.
