What “great debate”?
The back bullet hole had a halo around it which says it was a entrance wound.
If you don’t think a 161 grain bullet traveling 2000 feet a second can’t go through six inches of flesh, take a ham out of the tin and hold it in front of you. Have someone shoot it with a centerfire rifle.
I promise I’ll send flowers.
Your argument will be more convincing if you tell them to leave the ham in the tin.
