I think the victim is in more trouble because he spoke to the police without benefit of a lawyer.
Don’t talk to cops, talk to your lawyer and let him talk to the cops.
And whatever was stated on the 911 call.
That’s good advice generally but when a catastrophic event like this happens, people are more likely to give their version of what happened. A person who is justified in self-defense but then tells the police on the scene that “I won’t talk to you without first consulting an attorney” will automatically raise a flag of suspicion . . . maybe it wasn’t self-defense. Where it truly is “self-defense”, starting with those very words seems important, “fear for one’s life”, descriptions of any threatening behavior w words by criminal etc. and don’t talk beyond the facts. Shooting someone for being a stranger and in one’s garage seems not enough for self-defense. Could be manslaughter. It is not a position any law-abiding person would ever want to experience.
