Well, let me take a contrarian view here. I think the young woman was poorly served by her boyfriend and the instructor. Some of y'all are making some broad generalizations based on very little information; mostly that she was a non-shooter and had been handed a weapon that many "experienced" people shoot themselves in the butt with. The instructor should never have handed a loaded glop to someone she figured couldn't use a can opener. She (the instructor) should have spent whatever time was needed in familiarization before actual live firing. If the instructor determined that the trainee just wasn't up to it, she should have told her so, and suggested that she get a simple to operate weapon like a double action revolver.
Based on what information is in the OP, I don't think we should automatically assume the young woman is an air-headed idiot. Ignorance isn't the same thing as stupidity.
Another thing while I'm ranting: I do not like this attitude at all--"has me rethinking gun ownership and wondering if some people should not own a gun, much less be allowed to carry a handgun or even be granted a CHL." Who are you going to put in charge of making those decisions? The government? The ATF, FBI, or some other Federal Agency, many of whom shoot themselves in the foot or in the butt with their glops? I think it is a pretty arrogant attitude.
I have been shooting 50 years plus, and I have taught a few people the basics. I absolutely would not hand a glop or even a 1911 to a brand new shooter. If he/she came to me with a semi, I would say, "Let me loan you a pistol for us to get started with," and we would shoot up a couple of boxes of .22 lr in my Model 63. I would then try to transition over to the semi.
