Saying something "is the law" doesn't justify it. Justice, whatever that may be, certainly takes into account circumstances. It simply isn't fair to do otherwise. The man has a right to save his wife's life as long as he hurt no one else, which he didn't. Giving him ANY punishment would be unjust. The purpose of having law enforcement that is human and not robotic/automated is that humans, well most of them, have an inherent sense of justice willing to allow exceptions in drastic situations, which this was. That and we don't have the technology to do that, but my point remains.
