I think the cop is responsible for his actions. Gun or taser, he is paid to know the difference and when to use which.

In the end, he shot the kid. I've no idea if it was cold blooded or not - only the cop knows. But he killed a restrained suspect who was prone.

I agree with all you points. And that is why he is got convicted. And cold-blooded is usually attributed to those lying wait to kill, not those in the heat of battle. When all the civil lawsuits are over and BART pays out millions, I am betting it will be based on the training records and find a deficiency in the TASER training.
