Child access prevention law
A child access prevention law (often abbreviated CAP law; also sometimes called a safe storage law) makes it illegal for an adult to keep a gun in a place and manner so that a child can easily access and fire it. Proponents of these laws, such as the Law Center to Prevent Gun Violence in the United States, argue that they are effective at reducing accidental gun deaths among children, since they reduce accessibility and thereby risk.
