There are those who argue that concealed carry is a right under the Second Amendment and then there are those who argue that Open Carry can be banned in favor of concealed carry without violating the Second Amendment. But wait, there's less. There are those who argue that when the US Supreme Court said in the Heller decision that concealed carry is not a right and can therefore be banned without violating the Second Amendment, what the Court actually said was that Open Carry can be banned. Keep in mind that all four judges in the Heller minority also said that the majority was correct in saying that concealed carry is not a right and can be banned.
If you are one of those people then here is you opportunity to do what none of the so called gun-rights lawyers has ever done in any of their concealed carry lawsuits and that is to provide pinpoint citations to case law and other historical authorities in support of your argument.
There are several online legal databases which are free. The easiest to use, which is also the fastest, is Google Scholar. There is also Google Books which has a gazillion books printed before 1924 within which to search for your historical authorities to support your claim that concealed carry is a right under the Second Amendment.
A word of advice. If you are one of those people who claim that the Second Amendment protects a right to concealed carry because the plain text of the Second Amendment makes no mention of concealed carry then you should be aware that isn't a legal argument. To be sure it is an amusing argument to make, but not one any judge in any American courtroom would entertain, not even one who really, really likes concealed carry and who really, really hates Open Carry.
