But that's exactly what you're doing when you disallow carrying :P Your intentions can be great, but it doesn't excuse the fact that you are prohibiting people from carrying firearms.
And yes, we can get back on topic.
When I was LEO we had range training four times a year. As LEO we were to unload in our car or before ariving. We were not permitted to carry a loaded wepon to the range. Ammo was supplied at the range and we had to clear and clean our weapons before leaving the range.
So don't feel too butt hurt here.
