I let my CHL expire, now that glovebox guns are OK, it just seemed less important. I decided not to renew because I could not endure an entire day (that I can't get back) listening to a deputy constable from Podunk county, telling me not to play quick draw. I may invest 4 hours for a new one. One thing I would recommend strongly. instructors should explain in no uncertain terms that a CHL holder is not a Policeman. Is not endowed with arrest authority (more than any citizen). Has not been given a mandate to "save the world." All comments I have heard from new CHL graduates. Maybe this could be included in something you must sign. Just saying...
You'd be pleased to hear at least one instructor covered just these topics. In my class it was laid out the CHL is intended to cover you and yours. The way it was stated, was "everyone else has the same opportunity under the law to protect themselves, it's not up to you to be the hero." Then the issue of the costs of litigation after intervening were discussed. I think another quote was "if I'm in a crowded room where someone starts shooting, and there's an exit to my left? I'm taking it."
