Way easier said than done. To watch all the shooters you would have to have at least a 5 to 1 ratio of shooters to Range Officers. Very few ranges can pay for that, even with volunteers,who may or may not be qualified. In the end it boils down to the shooters being responsible for themselves, and as much as I hate to admit it, there is a segment of people who want to shoot guns who have not a responsible bone in their bodies. They are freaks, losers, and scumbags, but with a public range it is hard to keep them out.
