Someone who is within 21 feet of you acting aggressively and lunging is a threat.
Someone who is within 21 feet of you acting aggressively and lunging has opportunity.
Someone who is within 21 feet of you acting aggressively and lunging and not leaving when asked has demonstrated ill intent.

We don't have all the facts, but based on the story as presented i think FAFO.
Also a "real" company doing "real" business is just about meaningless.
Homeowner comes out to discuss. A dispute ensues. Homeowner returns to his home to get a gun, returns, fight continues, homeowner shoots supposed trespasser.
Castle doctrine only applies to home, immediate outbuildings and your car in NC. So it fails that test.
Stand your ground - your not obligated to retreat, but if you do you don't get to go back. The homeowner was originally unarmed - according to the article. He returned to his house, got a gun and returned. Its not stand our ground anymore, your the aggressor. Failed Stand your ground.
Also have to be in fear of imminent harm, and the response needs to be commensurate. Does anyone think a armed full bird colonel should fear an unarmed dude in flip flops so much he can shoot him. Failed stand your ground again.
Trespassing, or even trespassing and taking pictures, not something you can shoot someone for. No imminent threat.

No good came out of this interaction.
