Actually, Walter, Michael Brown was shooting at Officer Wilson with a heavy machine gun. When Officer Wilson bravely defended himself and the community, New Black Panther Party ninjas swept in, stole Officer Wilson's gun, fired the top-of-the-head shot, returned the gun to Officer Wilson's holster, took Brown's machine gun, swept up the brass, spackled the bullet holes, and replaced the shot-out glass on nearby cars, and used their mystical New Black Panther ninja voodoo skills to vanish, creating the illusion that Brown was unarmed when Officer Wilson killed him.
The operation was ordered by Obama and carried out by the New Black Panther Party ninja team controlled by Eric Holder.
