I was visiting a detention facility and at the entrance gate they had lockers with a sign "Keep you firearms here". Now that makes sense. You visit, you leave you gun and pick it up when you leave. But NEXT to the lockers is a half barrel of sand tilted over 45 degrees with the sign "Discharge your firearms here'. I mean, if you wanted to unload it don't you just take the bullets out and put them in the locker with the gun??? Why would somebody want to walk up to a jail gate and shoot into a barrel of sand??? Anybody? If I go there again I'm going to ask somebody.
