Newbies, we were all there once.
Being encouraged to do it right got us where we are.
Of course we should weed out those Alex Baldwin types with the totally wrong attitude about safety.
But, for those who listen, nurture them.
We owe that to public safety.
Is there Camel parkinā out back?
Do they know what a pair of Shoeās look like?
Doā¦oh forget it
IIRC the OP posted regarding customers at his range renting guns and being cut loose with minimal information on the rules at the range.
Thatās a liability issue, not a 2A issue to my way of thinking.
Itās somebody elseās gun. Itās somebody elseās range. It sounds like customers are disregarding the rules, making the range unsafe----thatās the issue that needs addressing.
Training is all well and good, but for a new shooter just getting their feet wet, or a foreign guest unfamiliar with shooting, the knowledge of safe operation is whatās necessary. Immersive training like perfecting shooting the *El Presidente, * not so much unless maybe you expect them to disassemble and reassemble a 1911 while blindfolded.
I think most ranges wouldnāt allow that. anyway.
My son works for foreign professional athletes who love competing is large US cities where they can rent gun$ and $hoot when they arenāt training or competing.
Heāll go with them and make sure they are playing safe.
I guess it all comes down to what you guys mean by training.
Not too costly when weighed against the fallout of a fatal shooting. The RSO should be viewed as an investment. Newbies wonāt return if they donāt feel safe, and negative publicity is a killer in its own right.
Iāve thought about this a little bit, OK, So weāre talking about the range renting a firearm to someone of unknown skills and experience and turning them loose. So letās change the script a bit, your neighbor knocks on your door, a slight built Gen-Z guy, salmon button down and Bermuda shorts. He just moved in next door. Seems like a nice enough guy, drives a BMW, has a Barbie wife and a pug dog in the backyard. He points to the area between your houses and says āSee those two trees? Iām going to trim that one and cut that one down, can I use you chain sawā¦?ā. What do you do? Hand him the Stihl and the gas can? Take him to the shed and show him how to start and run the saw? Maybe even give him the gloves and glasses? OR do you say āHeck No Brother, you aināt touchin my saw!ā? Same thing on a range with a gun. Do you teach how to handle the gun, do you give him the ears and glasses? OR do you send him away because heās ignorant? Notice, no Government intervention involved.
I donāt loan out my power tools (or my weapons) out to anyone. The liability of a possible malfunction of the equipment or the user is too great. I made that mistake one time and loaned my .303 to my ex-brother-in-law to go hunting. He said his .270 was āin the shopā.
So he gets out to his lease and climbs up in his tree mounted deer stand. He takes a bead on a doe, pulls the trigger and takes the doe down with a clean shot. He also dislocated his shoulder and broke his collar bone because my old .303 kicks alot harder than his .270. He drops the rifle to the ground and tries to climb down one handed with his backpack over his left shoulder, loses his grip and falls to the ground, landing on his right side, on top of the rifle, breaking three ribs. He grabs up his pack and the rifle, and hikes 2 miles out of the woods to his truck and drives to the hospital.
His entire family, my Wife included, blamed me for his injuries because it was my rifle and I didnāt āwarn him strongly enough about the recoil.ā
Hereās the kicker though. He was, at that time, a cop with local PD, and an instructor at their small arms training facility. He knew what he was getting into when he decided he wanted to shoot an old military rifle.
So, no more loaning out anything, ever.
Hmmmmā¦Barbie wife wanted a Trophy Husband, but it sounds like she got a participation trophy instead. 
OMG, Post of the DAY. Perfect!!!
Show his wife how to use the chainsaw.
D*mn it @John292 and @Karacal. What did I say about making funnies while I am reading a serious post. Liquids being forcibly expelled from my nose hurts 
.
ROFLCOPTER 
and HAHAHAmbulance 
have been dispatched to my location.
Peace
and 
I fail to see the humor. 
He didnāt take it to a range and put a few rounds through it to check the sights/scope first? If I borrowed a rifle from someone, Iām going to put at least 3-5 rounds through it before I take aim at an animal with it. Even if I grabbed one of my own rifles, Iād put a few rounds through it before going on a hunt.
I agree he should have, but he didnāt. I have never been in a situation where I need to borrow a firearm from anyone for any reason, but if I ever need to, I will send a few rounds down range first just to ensure the darn thing works.
Iām not sure Iād be comfortable borrowing a firearm or lending a fire arm for that matter.
OKā¦ IF (BIG IF) One of YOU Folkās wanted/Needed to borrow a spare AR/Weatherby etc. YES!
(Zero hesitation). But thatās as far as Iād go.
You need a replacement/ borrowed weapon? go buy one/ RENT ONE.
Another lesson (this Topic) learned without any pain for MOI ! Thank you
