I suppose that means you are confident that you are safe from the "Justice System" if you ever find it necessary to use lethal force against an intruder.
You may be correct in that assessment.
My own thought is that the shooting part of an incident is the least difficult. It is the legal aftermath that is most dangerous. The process is the punishment.
My own plan in such events would be to say as little as possible to the Police (call 911, give name, address, shots fired, quick description of aggressors, request medical assistance for them) and nothing at all to reporters, or anyone else.
The rest is a short formula:
"I was in fear for my life".
"I am too upset to talk about that right now".
"I will answer all your questions through my Lawyer".
Hopefully you never need to do any of that stuff.
Any intruder will be met with lethal force.
Your advice to cops is correct.
