It’s scientific fact. Read the book referenced in the Forbes article. When a person with brain damage can’t convert short term memory to long term memory but can form new habits, what’s going on? The what’s going on is a recent discovery.

meatloaf, dear -- I will not waste time reading a book that attempts to refute thousands of years of human experience in Western Civ that has always held adults accountable for their behavior, including one's teaching children by example to delay gratification and develop self-control. And that's not even to mention the successes of numerous recovery programs for people with addiction problems.

And even if the guy had a serious brain malfunction impelling him to kill at the first sight of flung popcorn, he is still guilty of manslaughter. He still was packing when he shouldn't have been. He still, by your own post, expressed horror at his own choices after he killed a man. And he deserves to be punished for not having developed self-control, especially after having sworn to "protect and serve" all those years. Face it. Even if he had run over a man with a car "by accident" because he's old, he would face jail time. And would deserve it.
