I mean, he was holding his camera with his right hand, walked in front of the vehicle and switched hands so he could take out his gun. He wanted something to happen and it did. I didn't watch Megyn's video above, but my opinion remains the same... absolutely unnecessary shooting, but also absolutely legal (technically) if a vehicle is driving (barely) towards a cop. If he really thought the vehicle was a risk he wouldn't have walked in front and switched hands so he could have a gun to shoot with.
