I was thinking, why don't they just shoot at the legs and bring him down, instead of the back. Then I recalled my brother-in-law telling me of his training in the CHP academy, of how hard it is to hit a specific area let alone any target on the move and they go for dead center when they shoot. Sigh, I watched too many Hollywood shoot-em-ups where they shoot the bad guy in the arm or leg to disable them. And from a hundred feet away!
On the other hand, maybe it's just a stereotype, but doesn't everyone and their mother own a gun in Louisiana? Don't you think a police officer in that environment would have enough famiarity with guns to be able to aim low?
