In particular, shootings involving the use of semiautomatic assault rifles have resulted in hundreds of lives lost, devastating injuries, and lasting psychological impacts on survivors, their families, and communities. Semiautomatic assault rifles are specifically designed to kill quickly and efficiently and have been used in some of the country's deadliest mass shootings, including in Newtown, Connecticut; Las Vegas, Nevada; and Parkland and Orlando, Florida, among others. Semiautomatic assault rifles have also been used in deadly shootings in Washington, including in Mukilteo and Tacoma.The impacts of gun violence by assault weapons fall heavily on children and teenagers. According to one analysis, more than two hundred eight thousand students attending at least two hundred twelve schools have experienced a shooting on campus since the Columbine mass shooting in 1999. Active shooter drills are normal for a generation of American schoolchildren, instilling at a young age the sad and unnecessary realization that a mass shooting can happen in any community, in any school, at any time.Enough is enough. The people find and declare that it is crucial and urgent to pass laws to increase public safety and reduce gun violence.Implementing an enhanced background check system for semiautomatic assault rifles that is as strong as the one required to purchase a handgun and requiring safety training and a waiting period will help ensure that we keep these weapons out of dangerous hands. Further, federal law prohibits the sale of pistols to individuals under the age of twenty-one and at least a dozen states further restrict the ownership or possession of firearms by individuals under the age of twenty-one. This makes sense, as studies show that eighteen to twenty year olds commit a disproportionate number of firearm homicides in the United States and research indicates that the brain does not fully mature until a later age. Raising the minimum age to purchase semiautomatic assault rifles to twenty-one is a commonsense step the people wish to take to increase public safety.Finally, firearms taken from the home by children or other persons prohibited from possessing firearms have been at the heart of several tragic gun violence incidents. One study shows that over eighty-five percent of school shooters obtained the firearm at their home or from a friend or relative. Another study found that more than seventy-five percent of firearms used in youth suicide attempts and unintentional injuries were stored in the residence of the victim, a relative, or a friend. Secure gun storage requirements for all firearms will increase public safety by helping ensure that children and other prohibited persons do not inappropriately gain access to firearms, and notice requirements will make the potential dangers of firearms clear to purchasers.Therefore, to increase public safety for all Washingtonians, in particular our children, this measure would, among other things: Create an enhanced background check system applicable to semiautomatic assault rifles similar to what is required for handguns, require that individuals complete a firearm safety training course and be at least twenty-one years of age to purchase or possess such weapons, enact a waiting period for the purchase of such weapons, and establish standards for the responsible storage of all firearms." [ 2019 c 3 § 1 (Initiative Measure No. 1639, approved November 6, 2018).]Short title—2019 c 3 (Initiative Measure No. 1639): "This act may be known and cited as the public safety and semiautomatic assault rifle act." [ 2019 c 3 § 2 (Initiative Measure No. 1639, approved November 6, 2018).]Effective dates—2019 c 3 (Initiative Measure No. 1639): "This act takes effect July 1, 2019, except for section 13 of this act which takes effect January 1, 2019." [ 2019 c 3 § 17 (Initiative Measure No. 1639, approved November 6, 2018).]Implementation—2019 c 3 (Initiative Measure No. 1639): "The director of the department of licensing may take the necessary steps to ensure that this act is implemented on its effective date." [ 2019 c 3 § 18 (Initiative Measure No. 1639, approved November 6, 2018).]
