If there was nobody around, and every cop knows about the 21 foot rule, why does he get within 10 feet? He puts himself in danger if he does that. And shoots the guy as he’s turning away?
He’s toast.
The cop says he had a knife and turned toward me. Well, no shit - you come up BEHIND the guy and yell at him, what a surprise that he turned toward you. This cop better start practicing picking up soap in the shower without bending over.
