The Anatomy of a Murder

From the comments to the following report 3 Officers Involved in Shooting at Summerlin Costco:

My wife and I were 7 or 8 feet away from the shooting as were the police. We were to the suspects immediate right. We heard and saw the 3 police officers shouting to the man in question to 'get on your knees' several times. At that point the man appeared somewhat stunned by the commotion and shouting of the police. His Right arm went up in a defenseless position and it appeared his left arm appeared to be going up but there was NO gun in his hand. He was taserd and shot at the same time. At no time did the man in question ever raise his voice, shout an obscenity or become confrontational with the police. We saw the disabled man stooping to his right facing us with what appeared to be a bullet wound in his upper chest with blood coming from the wound and immediately his eyes became glossy as he began to convulse. At this point he was no threat to anyone, both hands were in full view of us and there was no gun. As he was down, the police continued to shout 'put the gun down' several times...but there was no gun in his hand as we had full vantage point view. The injured man was having agonal respirations, he was down when the second volly of bullets rang out...
