As new gun owners enter the pool of sportsmen, hunters law enforcement and military veterans, they don't have the insight or experience to be left to their own demise, and that of other people who may be unintentionally injured as a result of their unfamiliarity with firearms and especially ammunition.
Most have no idea what a rifle bullet will do upon hitting a barrier or a person, or weather they have hollow point, or FMJ, Frangible, or wad cutters etc in their firearm.
They don't realize that having their finger on the trigger when someone yells, "HEY", and they turn and the gun goes off.
that's why you can't compare this to a chain saw. The person with the saw is likely to be the one who suffers for their lack of efficiency.
With 30 round magazines and buckshot, a small flinch can cause a major problem. There needs to be some kind of training for weapons that is perhaps not mandatory , but suggested for new gun owners, other than nothing.
Just because they sat through a class and fired 1 round, is not enough to make them safe around our family's and friends.
I don't even go to the range anymore because of all of the nonsense that I see with guys Putting a 44 magnum in their dates hands and telling her to shoot at the target, while she hits the ceiling and turns around with the hammer back sweeping everyone in the place.
As this turns into a more inclusive hobby, we are going to have more accidents due to lack of knowledge period. There is no respect given to the weapon by many a video gamer, who thinks they "got this", because they just killed 300 make believe bad guys in Black Ops.
I am and have always been for a reciprocal carry permit, open or concealed, for anyone who has not been arrested and convicted of a violent felony, or is not a citizen or handicapped in a way to make it unsafe to use a firearm. But I would prefer that they also spent one day out of their lives to take a course, on how guns function, what single vs double action means, how to tell a gun is not loaded, and what different types of ammo do and what their use is, along with the normal safety rules, that we take for granted they know.
