Here, an openly carrying person might be detained, but won't be arrested for the mere carry of a gun. As per the police giving bogus information, such as not being allowed to carry chambered/loaded, it happens on occasion. Again, the best thing you can do is become familiar with carry law(s). The police in general now have a pretty decent grasp of the right to openly carry, but there are many who aren't familiar with certain details: i.e; carry in an establishment that sells/serves alcohol, "pistol-free" zones, motorcycle carry, etc. Whether it's an insult to a LEO's ego or not, it's better to know the law better than he does. If you know the law and are illegally detained, the LEO looks like an ass and the whole department looks incompetent. This results in more training for LEOs, giving them a better grasp of what's law, which benefits all.
