A pretty good friend of mine had a situation a few years back.
He was coming home, a motorcycle was parked in his driveway and the guy was at the front door knocking, so he drove around the block thinking it was a salesman and he would just be gone when he circled back. Well the bike was still in his driveway, but the guy was no where to be found, his walk through garage door was open just an inch or so. He gets his .45 out of his pickup, has his son (9) to dial 911 and he walks into the garage. Sure as shit the guy is trying to bust his house door open, he shouts to him to get on the ground holds his gun towards the guy. Well fortunately the guy listens and gets on the ground and stays there.
Less than 3 minutes go by and there are a half dozen cop cars out there and they jump on the guy (roughly) and get him handcuffed and hall him off.
Story ended well for all involved. He sure did not want to shoot a guy, he didn't want his house broke into, he didn't want his son to see a guy get shot by his dad. The cops handled it, no one was injured, the house was safe, and no life changing events for the innocent.
Believe me you guys don't want to be shooting anyone if at all possible to not. Seems like putting a hole in a bad guy would be cool, and easy, well I know my buddy is damn glad it didn't come to that, it was hard enough the way it all played out.
