IANAL but from what I remember from a couple of law classes I took in college, this is probably a false sense of security because there doesn't have to be a complaint when you're talking about breaking a law in the criminal code. Think of it like this: there doesn't have to be someone to make a complaint when there's a murder. All it takes is one LEO or prosecutor who wants to make it an issue. It's the civil code that usually needs someone to complain.My personal rule of thumb is if no one is going to see one or more people at a location open carrying and complain about it, then it will not be an issue. It only becomes a problem if someone reports it.
It's been 23 years since I graduated so I may be wrong.
