So, CNN reported that the Officer is going in front of a Grand Jury. I don't know if that is still there report as it was a good 12 minutes ago and things change fast in this story. In jurisdictions I am familiar with Grand Jury Testimony, and evidence entered before the Grand Jury becomes presumptively privileged until an indictment issues or a no file is announced. I imagine many would think that a Grand Jury Presentment is a positive indication that the Officer may be seen as having some real exposure, but I suppose cynics could see it as further stonewalling.
Presuming for the moment that the Officer was in danger, and was justified in shooting (I presumption I do not make at this time) I am wondering why an Officer, already presumably punched in his face and somewhat incapacitated by injury does not call for backup, and why he leaves the relative safety of his vehicle. I also wonder how close he was to the relative safety of the vehicle when the deceased is proposed by some to have bum rushed him (BTW I thought bum rushing was escorting someone out with one hand on the collar and the other on the belt, a wholly misapplied phrase in this instance). If he was close to the vehicle he had a tactical option other than shooting. In other words though it is conceivable the Officer was within his rights he may still bear civil liability if his training dictated he pursue, potentially, other options.
I always like to look at situations through the eyes of a 5 year old. It offers perspective. In this case if you asked a 5 year old what is the smart thing to do when you are injured and maybe not seeing clearly, and you have a gun not made for bear hunting, and a bear is charging you from 35 feet away, and you are standing by the door to your safe car, would you shoot or jump in the car and lock the door; what would that 5 year old say? Who's got acess to a 5 year old
