For all my above, thats just general discussion.
This survey, seems to me fishing for reason for a higher level of mental health check from GPs. And shooters to pay for it.
When should the State demand GP's to flag up mental health issues? Do GPs police for driving; for being a teacher; for being a Policeman? Where should patient partiality somehow be State property?
Its a dangerous road to tread.
The Firearm Licensing system places enough demands with the GP part as it is.
Perfectly "sane" people can "turn" on the oddest and most random of reasons. Youth suicide shows that there is only so much that can be done, and eventually it comes down to the individual. For that individual to recognise they need help and then go and look for it. Many failures are after help was sort but not found. Licensing isn't much help, just a use of resources that could often be better spent where it really matters. It has very limited use.
I don't think being grassed up by their GP, and possibly losing their sport, is very inducive for people to be open about how happy and relaxed they are, or admit how much stress they are under. Most people have a chapter in their lives that isn't easy, but they don't all go silly.
Again, it all comes down to personal responsibility: to yourself and to society. I find shooting shorts are excellent in instilling that necessary self discipline and awareness. Most shooting sports are very sociable and very responsible. Air gun shooting an excellent stress reliever being a lot of fun. More people should be encouraged to take it up; and not more barriers put in their way.
