Supreme Corp: Ok to shoot an unarmed black man in the back

That's pretty much what they just decided. A cop pulled over a black man for drunk driving. When the cop went to put on the cuffs the man turned his back to the cop and started walking away. The victim claims the cop shot him in the back right away, the cop says the victim reached for his waistband and though he was going for a gun. There is an obvious dispute of the facts, which requires a jury trial. But the Supreme Corp sided with a lower court saying there is no dispute of the facts and so the lower court can just issue a summary judgment. Justice Sotomayor wrote the dissent.
