I was an Dept. Of Criminal Justice Training certified instructor from 1996 thru 2012 and no ammo was ever brought into my classroom. My classes were held in my home. When a student arrived the gun and ammo were stored in the living room. The classroom was in the basement. I inspected the guns for safe condition, as required by the regulations, while the students watched the video tapes. Later when the students were required to disassemble and clean their weapons, they retrieved the weapons and brought them to the class room and the ammo remained in the living room. When the range qualifications started, we all went through the living room to my range in the side yard and shot the required rounds. At no time was any ammo brought into the class room.-snip-
As I said for years one was required to bring ammo and gun to the classroom.
