It's easier to train someone to be safe with a firearm than with a chain saw or a car.
The training being easy is irrelevant. That doesn't mean that the individual will be more responsible just because the training is easier. It is totally dependable on the person. And even then people in general are irresponsible, but again the comparison from guns to anything else doesn't matter because every other thing has a use that isn't injuring or killing a living thing.
