Well, let's just say you need to be as discrete about anything you do in places like that. For example if you want them to know you have a weapon to deter them don't just walk out front like the st Louis couple, also wear a full face tactical mask, etc, hey at least masks are totally fine now. It's best to train yourself as much as possible so you never over use too much force, always de-escalate as much as possible, it's living on the edge and something I've experienced myself in California where it feels like you don't know what to do even if someone broke into the house I feel like I'm not sure if I should use pepper spray or a gun because it's a legal system massively weighted in favor of violent criminals.
