You don’t call something an aquittal unless both charges are decided “not guilty”. That’s a verdict and is announced.
I don’t know for certain but I’m under the impression you deal with the charge first that the state put forth and tried to prove. If all agree he’s guilty of that, it’s a guilty verdict. If they agree he’s not guilty or they can’t agree on that, they can choose to move to the lesser included of manslaughter but they do not HAVE to. That they would consider and deliberate on the lesser included means somebody in that room wanted to go there. We don’t know how many. Could even be just one.
talking heads saying they are thinking if just pulling a trigger in isolation is enough by itself for element of “intent”.
