My thoughts on a couple of topics
The problem is with where the poll itself exists. How many people with our rationale actually read the CNN web page? It isn't a fair sample. And that's why they can get any result they want. And, it will probably always read 2:1 against us no matter how many of you "vote".
As for me, I started shooting .22lr at age 7. I was closely supervised until I could prove I could do it properly on my own and be responsible. Man, how times have changed.
Yes, I believe that "SOME" 9 year old kids are capable of shooting a full auto. HOWEVER, that does not mean that "ALL" 9 year old kids are capable, and I also don't believe that there should be a law PROHIBITING anyone of a certain age from firing a certain type of weapon especially if they can demonstrate they can handle it.
From a very young age, I spent many a fun Saturday or Sunday shooting with my Dad and brothers when I was younger. I carried that tradition over to my own children and we have many fond memories of time at the range shooting all types of firearms. My youngest (17) told me not too long ago, that shooting was his favorite thing to do and his favorite memories are shooting with me. You can't beat that.
As for the machine gun range tragedy that occurred, the instructor is 100% at fault, and sadly paid for his mistake(s) with his life. The girl is a complete innocent due to her age, and probably doesn't even realize the full impact of what happened, but the instructor I believe made the following mistakes (not on purpose, I think he just got too relaxed in what he was doing):
1. He was positioned wrong. He should have contemplated every worst-case scenario - a run away being one of them - and adjusted properly. He should have been positioned more behind her.
2. He had a hands off technique which failed to restrain the recoiling weapon. He was unable to react to anything that went wrong.
3. He switched to full auto without instructing the girl what he was doing and the consequence of that action. Notice she immediately pulled the trigger as soon as he selected, and I believe he was not ready when she pulled the trigger.
4. The girl never demonstrated that she could properly support the firearm. She took one single shot from a bench rest position and it looked as if he never again required that she had a proper grip on the gun when the full magazine was fired.
5. Letting her take a single shot was a good idea, but the next step should have been to go to two rounds, then three etc., not a full magazine until she was more familiar. If there was a runaway, if only two rounds would have been fired, the second probably would not have caught the instructor in the head and it would have shown that the girl was not capable of properly restraining the gun from recoil.
