I don’t know what the law stipulates as punishment (if it was an error) so I can’t say what punishment he should get. Motive certainly IS key here. It’s far different to kill someone in a fit of rage than it is to kill them thru a stupid mistake. But, like you, I wonder if we will ever know the real truth, and our biases will color how we interpret what we saw. BTW I guess there is no audio of the incident. That would be helpful, if it was clear and close.
I agree. I don’t know what I would do if I was on that jury. We will never know...like you said it could be an accident or it could be 2nd degree murder.
