Nothing that I have proposed has anything to do with the “stand your ground” law. I think the “stand your ground” law, in general, is often misunderstood. I've had prosecutors say, “What you're talking about is 'stand your ground',” and then the judge acquits my client on a self-defence provision.

No, this isn't castle doctrine, another American legal concept that does not have application here.
