Prosecutors and defence lawyers agree on one thing about Marine veteran Daniel Penny’s encounter last year with a distressed, angry and threatening man on a New York subway: Penny didn’t mean to kill him.

But a prosecutor told jurors Friday that Penny “went way too far” in trying to neutralize someone he saw as a threat and not as a person, while a defence attorney said Penny showed “courage” and put others’ welfare ahead of his own when he placed Jordan Neely in a chokehold that ended with Neely limp on the floor.
