You should always do just what the police say, or they just might haul off and shoot you.
Agreed on doing what the cops tell you to do.
However, several witnesses give conflicting reports on what was said and done. (I was right in my recollection - everything from “drop the gun” with no gun in his hand to “get on the ground”.) And some eyewitnesses have a gun in his hand when shot, no gun, and gun in the holster.
I thought the “deer in the headlight” comment made sense. It may have taken Scott a second or so to realize all of the fuss was about him. And with regard to the surprise and shock and delayed reactions, a doctor also mentioned “no one tried to help him, including me - I was in shock”.
