Excuse me for saying but I think Sfmedic might be on the other side if you know what I mean. Every single training course places emphasis on safety, common sense and avoidance. The NRA is a strong advocate for avoiding problem situations and being safe. Just ask any NRA instructor or take one of their classes.
By now avoidance should be common sense and a trainer shouldnt have to explain avoidance to anyone. However all trainers explain responsible use and avoiding situations. Great pains are taken to emphasize these points.
If you dont know by now its a good idea to avoid a gunfight what can I say? The NRA teaches safe responsible handling all day long even when these ideals should be obvious and common sense to all.
