I know what "grazing off" means, and that's the problem here. ICE doesn't need to practice on aim, it needs to practice on proper police protocols in which you do not shoot at people running away from you if they are not making an immediate lethal-threatening movement. We do not want cowboy cops on the streets shooting bullets for no reason. ICE could have killed an innocent bystander. Based on the known facts so far, ICE was deeply in the wrong.
