I'll probably disagree with the decision that "no crime was committed" - you can't just shoot someone in this situation; shooting people is dangerous, it can lead to death. This man did not deserve to get shot. A reasonable cop, if he felt threatened, realizes what is happening and asks him (loudly, is fine, like he did), "hands up, out of the car" without firing his weapon. Run around the side to get a better view. When you're holding a gun, firing it could end someone's life. It shouldn't be taken lightly.
