The kid was down and was no longer a threat. We have the right to protect ourselves, not the right to act as an executioner. He is guilty of first degree murder in any court in the country. Have you seen the video?
I couldn't really care less. They tried to forcibly STEAL money from hard working Americans, on private property that they put their a$$ on the line for. And while that doesn't give you the right to kill someone, I won't miss seeing little Jaquavius on the news after he robs 7 more places and kills 3 people.
