"He was six stories up, but the road was heading down under the railroad, and the vehicle was moving directly away at around 5 MPH or so, so whatever elevation changes or lateral movement was minor for an under 150 yard shot."

I dont agree that the angle of the street was such as to make the shooter on a flat plain with the target. Also the vehicle's speed did not remain constant thus further hindering the shooters ability to properly lead the target. Also, it would seem that the first shot would've been the headshot and not a last shot. Also consider the first shot was a hit...the second a complete miss and the third a dead on headshot? There was no progression in accuracy [to be expected]. Also all three shots would've struck the target if it were not difficult from the AOA employed.

No.

Too many variables [listed throughout] converging in a very compressed and highly stressed time frame for me to accept a poorly disciplined, highly incompetent pizzabox making the shot.

Your chronology is wrong. The first shot missed.

Also all three shots would've struck the target if it were not difficult from the AOA employed.

The first shot was deflected by an intervening tree branch.

So you think shots came from the 'grassy knoll'? I was there, and saw that position. It would have been an easy shot from there, no doubt. Somewhat straight-on, slightly down angle, and less than 150 feet.
