While I'm sure having a weapon on your person is legal in all 50 states (with the possible exception of NY can you tell me what your take on the following situation would be. Lets say your friend is a jeweler and he works from home running small website. He doesn't conduct business at his house he rents a box at the local UPS store and has a phone number listed to that address so no one and no website or search engine has his home address listed in relation to the business, no customer has ever been to his house and he's never told a customer where he lives or to stop by anytime and take a look at his items. He's at home alone one weekday working in his basement office with say $10,000 worth of jewelry in in plain view in his living room but he's not expecting anyone over and has no reason to think anyone would be coming over his house for any reason whatsoever. So while he's in the basement working on something or other he hears what he can only describe as someone beating the crap out of his front door, he's got a Ozzy DVD playing in the living room and it's on pretty loud so suffice to say whoever was at the door was beating the crap out of it. He grabs a nearby weapon (think scary black rifle) goes upstairs peeks around the corner and sees two dirtballs pounding on his door. These guys are described as tattooed shaved headed punk looking miscreants. He cant get to a cell phone or a landline without them seeing him so he walks right to the door opens it and orders them off his property, he's pretty scared, sees something shiny in one punks hand and the other mope has his hands in his hoody pockets. They don't retreat instead they yell something over the stereo, he again orders them to leave and once again they don't retreat and the one in back makes a fidgety move and once again my imaginary buddy (who may or may not have raised his weapon by then I'm not sure) once again orders them off his property. They comply... he's a bit shook up, goes back down to his office and for whatever reason it clicks who those two dirtballs were. They saw something on his website and wanted to buy it locally (but never paid) and long story short he told them via email no sale was going to take place and he didn't want them as a customer and he though that was the end of the story. Back up a bit it turns out these two guy apparently went to the UPS store address he had listed and somehow put two and two together and showed up unannounced at his house. He came back home the next day to a message from a detective which he returned and he's waiting for a call back. He assumes these two mopes reported him to the police. Question is is the person in this story potentially in trouble and how should he explain his actions to the detective to make sure the correct side of the story comes out. PS Once they left I don't know why he didn't report an attempted home invasion, I guess he figured it was over at that point or probably figured out who they were during the ruckus and figured they were gone so no harm no foul.
