My outdoor club has a 3 second rule...to appease all the homeowners in the area. I am just a member; I didn't help make the rules! They do waive the rule for competitions.
I took the range safety officer course a few years ago for my hunter education certification. I must have missed the part about implying that you will be shot for disobeying range commands!
My brother is in the process of opening an indoor range; we are just waiting
for the occupancy permit after a lengthy remodeling of an existing range.
I will be working with him in running and managing the facility. One of our goals is to create an environment that is friendly, clean and safe.
I assure you that the owner of any business would want to know about threatening or disrespectful behavior towards patrons. If I were informed that an employee acted as described, he/she would hit the bricks.
Forget the criminal prosecution; you were not the aggrieved party. You were a witness to a possible criminal act, but it would be up to the 22 shooter to press any charges. Let management know, in writing what you saw. Request an answer; if they side with their employee, then find another range.
Good luck and good shooting!
