• The dashcam footage released on Saturday shows Mr Scott getting out of his car and walking backwards with his hands down. It is unclear if there is anything in his hands. Four shots are heard and he falls to the ground.
  The bodycam footage shows Mr Scott outside his car with his hands down but does not show the moment of the shooting.
  The BBC's Laura Bicker in Washington, who has seen the video, says it does not clear up the key question of whether Mr Scott had a gun, or if he pointed a gun at police.
