JollyRoger and Stevie-Ray nailed it. The purpose of the CCW class is not to teach you the mechanics of shooting. It is an educational class covering the legal aspects of CCW with a proficiency exam of basic marksmanship.
As others have said, after seeing the lack of shooting skills exhibited and the gung-ho Rambo attitudes of my classmates, my wife and I are more leery of other CCW holders than we were before we took the class.
The best part of our class was the instructor telling us all his nightmare stories of what does happen to law abiding citizens that do shoot a BG.
