As an NRA certified firearms instructor, we are not qualified to instruct students on the legal aspects. Students have to remember that we are not attorneys. Firearms instructors are qualified to instruct in the safe and proper use of a firearm and shooting fundamentals. Some are also qualified to teach tactical aspects such as cover, concealment, weapon retention, mindset, etc, but its always important to keep in mind that most range facilities and similar environments have specific liability exclusions that allow them to pretty much only hand out a copy of the legal statute, internet links, etc, but certain aspects of liability insurance preclude instructors from commenting on legal aspects.
The number one thing that we are taught is not to comment on what is beyond our scope of training. Students are instructed to read the statutes carefully and are provided with the tools, but if a student asks for example?
" If someone comes at me with their fists, is it ok to respond with lethal force?"
Most statutes refer to "eminent threat to life and limb?", etc.
We cannot comment "yes, of course, Your life is danger!!"
With regret, we live in a very letigious society and alot of instructors get into trouble for saying things to students that they cannot back on the witness stand.
