If Smith had survived, Smith would likely have been charged with the death. Smith is the cause of the home invasion, and Smith forced the officer to fire.
I agree with the first statement, and disagree with the second.
I'd say that Smith was root cause, with assistance from a judge that released him. And Smith gave the officer the option of shooting him.
Training and Situational Awareness on the ground, in the real world really, really sucks for lots of constabulary. There are exceptions.
I'm very careful around them, because a startled cop is a dangerous cop.
