I tend to find that CPL classes contain more opinion than legal facts and clear interpretation. The best attitude is to take the class to fulfill state requirements, and see professional handgun training, and professional legal advice. When you mix those two into a one-day class that combines the opinions of a "gun expert" and a "legal expert" (often a police officer or retired officer), so much BS gets thrown around that if you hang onto every word, you will walk out more confused than when you arrived.
Ill go head to head with ANYONE who thinks they can show me a valid piece of legislation that would prohibit a citizen in legal possession of a handgun from openly carrying it.
I would say that a brochure could be made and an attempt could be made to get these into the hands of CPL class instructors.
Fact is, a CPL is a expansion of your rights, and you surrender no rights to carry by having a CPL.
