AlexandrerA (Virginia): The right of self defense does not include the right to intervene on others' behalf.
That is not how Tennessee self-defense law reads. It includes defense of self, family and innocent third parties.
AlexandrerA: As far as rising to your rhetorical bait, you show me how someone who is was in the backyard of a house and is then encountered "jumping the fence" is not fleeing.
If the home invader is turning with a gun in his hand, how is he "fleeing"? He's a threat. AlexanderA using the phrase "rhetorical bait" ... are you at all self-aware? Stop before you shoot yourself in the foot again.
AlexandrerA: ... carried to its logical conclusion, this thinking means that every armed civilian is an auxiliary policeman ...
Technically speaking, under the power of the county (posse comitatus) the county sheriff could deputize me, even if only to order me to stand down.
Chicharrones: The neighbors weren't friends. They were family.
There you go, bringing background research and facts into an argument about the poetic truth of hypothetical arguments, Commenting on the facts rather than the comments. Tsk tsk. How un-internet. (Love your avatar).
back to AlexandrerA: The stated justification for carrying weapons -- by civilians -- is self defense, not the defense of others or general policing.
The law justifies use of force in defense of self and defense of others, the topic of the opening post.
Did the man in OP defending his family do any of the things that fit the definition of "general policing" (patrolling the public streets, responding to calls of crime in progress, interrogating witnesses, being on the lookout for suspects, arresting suspects and taking them to jail)? Uh, moving the goal post after being caught wrong on defense of others. Tsk, tsk.
And the gangsters who home-invaded the Biệt Động Quân veteran's family, Biet Dong Quan, Rangers of the Army of the Republic of Vietnam, trained by American Special Forces and Ranger advisers. Poetic justice.
