So which is more important, building the sport or safety?
I have never seen ignorance of the law stand up as reason not to follow it. I set up a new shooter safety certification course at our club and run a match specifically for new shooters. In the year we have been doing it I can tell you about 1 in 5 new shooters at the PSSC is ready to try this kind of match before the class. The other 80 percent need to be taught what is safe and what is not. About 1 out of 5 should not be allowed to participate without more, much, much more experience and training and testing. We routinely ignore the warning signs of shooter danger in order to get bodies onto the range. I see shooters who have been competing for years and decades who do not know the rules, are not safe and are not going to pick them up by osmosis.
Don't be in a hurry to get your buddy into a match. Take him out and teach him, see if he's capable and safe and if he's not, make him be or don't bring him out!!!
This sport is hard and very stressful. Don't throw new shooters into the water to see if they can swim.
Dang Rob, you must have been extremely bored to be on here!! I'll send Holland back out to Arizona to give you something to do!! I think he likes having to buy your lunch!
In my opinion they are equally important. Without the sport, you don't need the rules, right? I like the idea of a more intensive new shooter briefing. Obviously you can't cover everything, but something more than the usual "breaking the 180 and keeping your finger out of the trigger guard while moving" would be great.
