If I had suspicious people trespassing on my property like in SLC's situation, I would most definitely walk out of my house with a 12 gauge pointed to the ground/air. We aren't talking about someone living in the suburbs and walking 20 feet down a driveway mistakenly. We are talking about a chunk of property with a long drive and they had to unlatch a gate to get down and wander. You can tell the difference between someone friendly or needing directions/help and someone shifty. These people parked out of sight, instead of pulling up to the house. They weren't looking to say hi. I'd send a gruff looking dog out first, and then follow behind with a shotgun. Personal preference.
