tom,
Let's put this in the context I deal with. I teach several different things. Before I start I make sure you realize that there are laws, rules, and regulations that your are bound to. If I am not quoting the statute, etc. it is my opinion, and you are entitled to my opinion. Regardless of my opinion, or your understanding of my opinion, you are still bound by the law, rule, or regulation.
If I were to have someone referencing me with my permission I want control of that statement. Without that control I am not responsible for anything they say.
In a case of Carry classes, if a student is involved in an incident based on that Permit to Carry and they go to court, I WILL be called in to explain my roll in the training. The National Rifle Association can face the same either in court or the court of public opinion. If they do not control the message they will not let it be represented as their message.
Yes, it is 100% defense against the Weasel.
