Daily Range management is an intense undertaking that requires constant vigilance and supervision by competent range safety officers. Unfortunately most public ranges are not able or are unwilling to provide that level if supervision. I conducted a lot of courses on my range and was astounded by the lack of knowledge and discipline among folks who had been shooting at public ranges. There is a big difference between stupid and ignorance. I can correct ignorance, can't fix stupid. A lot of folks just need someone to take the time to teach them proper safety protocols. Stupid just gets you sent home.
