Even if the traffic stop was bogus, and I still believe it was, I'm not sure how one can refute the bad moves in the video. I didn't see a guy being lured out to talk. I saw a guy who lost vehicle control while evading a blockade, then jumped out of his vehicle, moving quickly and erratically, and moving his hands all over the place.
Even if it was all a total setup, had he stayed in the vehicle like everyone else, or moved slowly and kept his hands up, he'd likely be alive today. He also fell back, not forward. It looked to me as if he was shot as he was turning towards the shooter, while his right hand was down in his coat.
Whether LE was right or wrong here regarding setting up the arrest, think about how you would react if say, you found an intruder in your home and you told him to put his hands up. If he started waving them around, or turned toward you with one hand positioned where a gun might be, what does your defensive training tell you that you should do?
I think there is still a valid argument to be made that LE could have used different means, a different location, or both if they wanted to make a peaceful arrest. Or that they could have waited the protesters out longer. But given this particular time snippet of this particular incident, it's hard for me to refute the argument that the dead guy made several bad decisions before he was shot. Even if LE was totally in the wrong, his self-preservation mechanism should have kicked in, especially if he thought LE was looking for any excuse to shoot.
