The section of the law you are referring to speaks to things that are not specifically authorized by the authority of license. That doesn't mean that everything else not listed in that section is good-to-go.
Other activity is regulated by other parts of the law....as in open carry of a loaded firearm. Those sections do not differentiate between intentional display and accidental display.
Would you do me a favor and link me to the section of code that outlaws this? I'm not saying I don't believe you, I just had some trouble finding it myself. I don't think the law says what you're implying it does, but I am having an issue displaying this.
