From the link:
The boy then slowly moves his hand to his waistband and lifts his shirt to show cops that he is removing the weapon tucked into his jeans.
'Get face down on the ground,' cops order as Rodriguez removes the weapon and drops it to the floor.
'Oh, don't do that!' a male officer says to the kid as a female cop orders him to get on the ground and 'drop it.'
Rodriguez then reaches in his pocket in what appears to be an attempt to remove something else, as cops scream and multiple gun fire shots are heard.
Lets be clear here. The instructions were GET FACE DOWN ON THE GROUND, not reach into your pocket.
Thats why this fifteen year old kid was shot. These officers have no way of knowing what this kids intent was by making such a move.
