A 1997 study found that CAP laws were associated with a 23% decrease in accidental shooting deaths among children younger than 15 years old. A 2000 study found that
Florida's CAP law appeared to have "significantly reduced unintentional firearm deaths to children", but that the similar laws that existed in 14 other states did not seem to have such an effect. At the time, only three states in the U.S., including Florida, allowed those who violated their state's CAP law to be prosecuted on
felony charges. A 2004 study found that CAP laws were associated with a "modest reduction in suicide rates among youth aged 14 to 17 years." A 2006 study found that states with CAP laws experienced faster declines in accidental child firearm deaths than states without such laws. A 2015 study found that these laws have no significant impact on unintentional gun deaths, but that states with such laws had lower rates of youth suicide. Another study also points out that prevalence of guns might possibly affect suicide rates in general. Some studies have also found that CAP laws are associated with lower rates of nonfatal gun injuries among children under the age of 18. A recent 2020 study differentiated between states with stronger CAP laws and states with weaker CAP laws and found that stronger CAP laws were associated with a 13% reduction in all shooting deaths among children younger than 15 years old, with a 15% reduction in homicides, a 12% reduction in suicides, and a 13% reduction in accidental deaths. A 2018
National Bureau of Economic Research paper found that CAP laws were associated with a 19 percent reduction in juvenile firearm-related homicides (while having no association with firearm-related homicides committed by adults or with non-firearm-related homicides committed by juveniles). In contrast, a 2016 study found that these CAP laws were ineffective. A survey published by
Johns Hopkins Bloomberg School of Public Health estimated that 54% of gun owners in the United States had unsafe storage of guns. Additionally,
Harvard T.H. Chan School of Public Health has estimated that some 380,000 guns are stolen annually from gun owners in the United States. In a separate study, the
US Bureau of Alcohol, Tobacco, Firearms and Explosives estimated that 18,394 guns were lost of stolen by licensed gun retailers. According to the article on "child access prevention law", There are different level of laws that are enforced when it comes to CAP, but the highest and probably most severe one is the laws that inflict criminal liability when a firearm that wasn’t kept in a safely manner is gained access to by a child. The law says that if a gun that was negligently stored get used by a minor to injure or kill someone, the owner of the firearm will be responsible therefore he will be fined, put to prison, or even in some cases both. CAP laws, along with other strict firearm laws, are also associated with lower rates of unsafe gun storage among parents of preschool-age children. These laws are not always applied whenever they could be, and sometimes minors are charged instead. In regard to the effects of CAP laws on schools, a study using data from the Youth Risk Behavior Survey for 1993-2013 found that CAP laws lead to an 18.5% decrease in the rate of gun carrying. The study also found a 19% decrease in students being threatened or injured with a weapon on school property. As July 2004, the
US Secret Service and US Department of Education published a study examining 37 school shootings from 1974-2000 that found that in more than 65% of cases, the attacker got the gun from his or her own home or that of a relative. However, the study finds no evidence of a link between CAP laws and an increased or decrease in school shootings. == Opposition ==
