“And more importantly he’ll get his rifle back”
I would find that hard to believe.
Do you think he would still want it?
If I were in his shoes I would ask that it be destroyed.
Assuming he is now the owner of the firearm, why suggest rejecting or destroying it?
The firearm worked as designed that night and saved his life multiple times. The weapon was not used in a crime. On the contrary, it served to prevent him being murdered.
It’s not Kyle’s rifle anyway.
