60 students seems awfully high, unless they are armed professionals of some kind( leo, guard, miltary and etc) even if say 1% of your class takers need to defend themselfs. ( which would be way high for the public , but about right for leos) that would mean you would need to train about 6k people a year. Which is alot. Even if you work 300 days a year, thats 20 new people a day. that has to be for professionals. ( or its bs).
