I do not practice any more but normally state laws would control and can differ. Usually not a good look when suspect is shot twice in the back. There is a question whether suspect or victim depending on end result, was in process of committing a crime and endangering a life. Things like this are not, in my experience, as cut and dry as people would like. Fighting with police, grabbing and taking away one of their lesser means to subdue you and running away as not a good look wither. Turning and the taser discharging is not good look either.
When I practice the biggest issue actually was, who am I representing. Since I am not making money remember you get what you pay for. This is more than a legal case to the public with expectations that might already be lost. I think the officer has been charged with "Felony Murder". I heard that is punishable by death in GA. Death cases are hard. Jumping out to me if I was getting paid to defend accused is what the **** felony was he committing at the time the death took place. Not sure about GA law but if the accused/officer needed to be committing a felony then he is probably walking and more trouble will be a coming. Why they charged him this was I do not know. Maybe grandstanding by prosecutor of maybe doubt they can convict on issues of excessive force, or maybe want the "biggest" crime they can find. I have no idea if the cops committed a crime,, but if someone gives me 3-1, I bet he walks because is not charged with a crime he might have committed. As always, it depends on the attorney he gets. While all men are created equal and are equal in the eyes of the law, all attorneys are not.
