The video indicates that the black man was being escorted back to his car by two officers and then two more officers joined in.  Next thing that happens is that you can see the black man falling to the ground and a voice can be heard saying, "he's been tasered."  Then a female voice chimes in and says, "Shots fired."  A white officer is seen pointing his gun down at the black man who has been tasered.  If this is the case, the officer needs to be found guilty and given the death penalty.  Let this be a lesson to all police officers that you can't gun down a citizen who clearly had his hands up, then was tasered and no threat whatsoever.  I predict more police shootings are around the corner.
