What is it that some people, including Mr. Peruta's attorney, do not understand? Laws do not grant permission, they only deny certain actions. If it's not denied by statute, then, by default, it's legal. Murder, be it for vengeance, vendetta, retribution or whatever, is illegal because the law states it's illegal. If not made illegal, it would be, by default, legal.
The statute requires a license to carry a firearm. The statute does not state
that the firearm has to be concealed, or unconcealed. Ergo, ipso facto, and a bunch of other dead-language terms, open carry is not illegal since it's not specifically prohibited by law.
The question to be raised is, where does some state agency get the lawful authority to add concealed carry restrictions to the law? And, if they lack the authority to do so, then why are they doing it?
