I might argue that it is you who is in the hole. You've been won over by the emotional argument that shooting is dangerous and so requires training, control, little men in charge etc. Now you are in that hole you can't see past the tabloid "sound bites" to the actual facts.
The only reason to have training is to address a need. Recently I did a FoI request to the SNH (old DC) asking about the number of deaths due to eating venison, due to firearms being used by a stalker and the number of reported animal welfare problems caused by legal deer stalkers.
In all cases the reply was that they were unaware of any instance, ever, where someone died from eating dodgy venison, where someone died in a firearm related incident whilst stalking legally or where there had been a report of an animal welfare issue relating to a legal stalker or legal stalking.
So, if there are no quantifiable problems exactly what problem is your training going to address? Exactly how will you measure the success of this training in terms of any reduction on zero problems? Exactly what will the training teach people? Statistics indicate that about 141 people die each year in accidents involving their trousers so perhaps these courses that you think we must all do will focus on how to safely put on our trousers before going stalking? That is the only area where I believe you could achieve a quantifiable and measurable improvement in performance through forcing stalkers to undertake training.
Despite saying this I'm not opposed to training at all, I have DSC1 myself for example, but I suspect that the deer stalking world is wonderfully self regulating in the sense that those who need training are getting it of their own accord while those with lots of experience feel no need to get it. This is supported by the figures - zero deaths and zero animal welfare incidents relating to legal stalking use of firearms or venison handling.
There is simply no basis for any argument that shooting or stalking are dangerous, in any way, to the stalker or the general public. Not only is there no evidence of risk and danger but in truth the evidence indicates the opposite - when I go into the forest or onto the hill with my rifle I am many times safer than when I'm putting on my trousers.
