Lol. Looks like they had to strain to come up with a theory for why that one was “self defense”. But all’s well that ends well.
That is why you say nothing to the police. You let your lawyer do the talking, because it is his job to keep you out of trouble.
Being the Chronicle, I’m surprised they didn’t just report that the customer shot the poor perp without reason. To include that the customer feared for his wife’s life is a detail I wouldn’t expect from this rag.
“Strain”? An armed robber points an AK at you and you shoot him? That’s not “strain”, that’s heroism.
