I do know of an incident that happened about 2 years ago. A guy and his brother set a target frame out at the 200yd area before shooting started for the day. After a while he wanted to leave and told the RSO that he was going to go out to the 200yd area to retrieve his target frame. The RSO told him that he couldn't go out there until they were able to coordinate the line safe with the pistol range. And that it could take as long as another hour before they could do it. The guy decided he didn't want to wait that long and at the next rifle side line safe (while the pistol range line was still hot with shooters firing) he went out to the 200 yd area and retrieved his target frame. The police were called and the guy was banned from the range for a year. The guy's brother was kicked off the range for the day. Bottom line is the brother got kicked off the range for the day due to this guy's actions and/or his attitude about his brother being banned. My memory is not always good so any details I may have missed or got wrong were done so purposely.
In my case, the only "attitude" was on the side of the RO. I was respectful and not making excuses. He, however, was adamant about trying to scare me with the "you're responsible for her" line. I think maybe I wasn't afraid enough for him. He seemed to be waiting for some attitude from me and didn't get it. At that point, I think he was disarmed and therefore walked away mad. Just seemed to want me to react and was not expecting me to diffuse the situation so easily.
If the act he saw was so dangerous, I fully expect he (if it was actually he that saw it) would have jumped on the mic immediately. Approaching me to tell me seemed odd.
I'm really not worried about being banned, even for a day. I do what I'm supposed to. If that's not good enough, then they can just ban me now! I can't do any better, and I'm too old to back down in fear just because someone threatens to kick me out for a mistake I never even witnessed.
So, this thread can probably rest in peace. It's gone much further than I expected already!
