As the video ends, "Martin" is shown lying prone, dead on the groundThey got that part right.
Here endeth the lesson.
Actually I'm not sure they got even that part right!
I watched this piece of propaganda twice, and it looked to me both times as if its producers portray "Trayvon" in his last appearance crouching in fear, but alive ...
... then the camera pans to rows of other symbolic "Trayvons" ... but they are all lying on the ground in the supine position, not prone.
