A safe culture is a one the majority adhere to. Where people don't carry a gun in public, the guns are locked in a gun cabinet when not shooting vermin on their land or at a pheasant shoot etc.. Pellets and bullets must be contained in the land where they have permission or received permission to shoot. That the reason to hold a firearm is legit, so they are part of a shoot, gun club, have land to control vermin etc.. Wanting one for self defence makes makes that person unsuitable for a firearm. Semi automatics are banned. Police hold amnesty hand in days for illegal weapons. Background checks are thorough, your driving and medical history are taken into account. Serial numbers are recorded and sales logged on forearm certificates and with the police.What exactly does a safe gun culture mean to you?
If an invading countries starts a war, you have a firearm(s) in your cabinet.
I don't know anyone personally who was declined guns. I only know one that sold his shot guns a few months before he died of cancer, otherwise they would have had to be handed in, or his wife apply for a shotgun certificate.
