I think the thread is mis-titled. This isn't really about what he said to the police, although that will certainly hurt his legal defense. It's far more about the way he acted, a way we cannot support.
Please, defend yourself certainly, but shoot to put a stop to the threat, not to kill. If your stopping kills, so be it. But never, ever, ever act like this guy.
As gun owners, we must be prepared to address the antis over things like this. We must support his right to self defense but condemn his escalation into execution.
