I witnessed a case yesterday of an "instructor" who was propagating excessive derp.
Trouble was ,he's one of the few local instructors in the area , so most of his students would probably have opted out if they had to travel and spend additional funds going somewhere else.
Would it be better in the aggregate for a totally untrained person to handle guns and learn OTJ, versus taking a class from a total incompetent who leads them wrong ?
In an ideal world everyone could afford a spot in a Scott Reitz or Tom Givens class (to name two ) , but we don't live there.
