The accidental deaths of children accidentally shooting themselves or siblings (or parents accidentally shooting family members while cleaning the guns) garner the headlines. These are tragic. But what's needed is education so that owners know the importance of keeping these guns stored safely and out of the reach of children. If you live in a high-crime area your family may need a gun to protect themselves.
Overall, the problem's really insignificant. The intentional shooting deaths (gang-related, murders and suicides) dwarf the number of accidental deaths and that's what we should be focused on minimizing.
