I had one nut job in my class. We were all asked to present our firearms for inspection and also so they could be displayed to the class to teach the various brands, types, operations etc. We were very strictly informed no loaded mags or ammunition on the table or within reach. Well one guy chose to ignore this and pulled out his loaded mag while the instructor was talking and proceeded to stick it in the mag well, drop it back out and repeat just for a something to do kind of thing I guess. The instructor let this happen about three times before he removed the magazine from the guys possession until time for the live fire test. I will admit the guy was making me nervous as well.
