It does look like execution. It does look like he wasn't holding any weapon.

If that firearm went off, what do you do? What do the officers think is happening?

There's no ignoring the reaction to a weapon discharge. If that shot isn't from that gun, then ballistics should confirm if that weapon was even fired.

If you are the defense attorney,you will look at this possibility.

If it happened,the grand jury would too.

The guy was shot multiple times.

Was there a discharge of his gun by the officer holding it?

Without that discharge, then did someone think he was reaching for a weapon?

Someone started the shooting. One pull is all that was needed for them all to shoot.

It comes down to why?

Prosecutors and defense attorneys will need those facts.

It looks like cold blooded murder. As we wait, more comes out.

There has been more analysis of the potential discharge of that gun. The history of that gun is still recent.

As a juror, what would you do if that gun went off and that happened?

The last jury I was on, one juror felt someone had to pay, despite self defense was established. That's the attitude that must park outside the deliberation room.
