What if you had the guy on the ground prone, hands behind his back (cuffed IIRC), and shot him in the back? Do you think your sentence would be higher?
I’d call that downright Mehser-able.
Just FYI, Mr. Grant was not handcuffed and did not have his hands behind his back. On the contrary, he insisted on keeping his hands in front of him, hidden from view, placed near the waistband of his pants. You may or may not think that matters, but we can at least keep the facts straight.
