This is just plain not true:
"Most of the injury and death created with guns is not attributable to madmen or criminals, but to so-called "law-abiding gun owners" who are irresponsible with their firearms."
Most murders are committed by felons:
Nearly all gun deaths are either homicide or suicide.
And it's already illegal to leave your guns where kids can get them. The other "safety" laws are mostly about making it difficult and costly to own and transport guns. They create a maze of hard to understand rules that turn harmless people into criminals. If it was about safety, you'd just get ticket, like when you drive in an unsafe manner.
Like in CA, where you can transport a gun in your trunk, but if it's in the back of a hatchback it also needs to be in a locked case.
