1 AN ACT Relating to establishing firearms-related safety measures
2 to increase public safety by prohibiting the manufacture,
3 importation, distribution, selling, and offering for sale of assault
4 weapons, and by providing limited exemptions applicable to licensed
5 firearm manufacturers and dealers for purposes of sale to armed
6 forces branches and law enforcement agencies and for purposes of sale
7 or transfer outside the state, and to inheritors; reenacting and
8 amending RCW 9.41.010; adding new sections to chapter 9.41 RCW;
9 creating a new section; prescribing penalties; and declaring an
10 emergency.
11 BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
12 NEW SECTION. Sec. 1. The legislature finds and declares that
13 gun violence is a threat to the public health and safety of
14 Washingtonians. Assault weapons are civilian versions of weapons
15 created for the military and are designed to kill humans quickly and
16 efficiently. For this reason the legislature finds that assault
17 weapons are "like" "M-16 rifles" and thus are "weapons most useful in
18 military service." Assault weapons have been used in the deadliest
19 mass shootings in the last decade. An assailant with an assault
20 weapon can hurt and kill twice the number of people than an assailant
21 with a handgun or nonassault rifle. This is because the additional
p. 1 SHB 1240.SL
 1 features of an assault weapon are not "merely cosmetic"; rather,
2 these are features that allow shooters to fire large numbers of
3 rounds quickly. An analysis of mass shootings that result in four or
4 more deaths found that 85 percent of those fatalities were caused by
5 an assault weapon. The legislature also finds that this regulation is
6 likely to have an impact on the number of mass shootings committed in
7 Washington. Studies have shown that during the period the federal
8 assault weapon ban was in effect, mass shooting fatalities were 70
9 percent less likely to occur. Moreover, the legislature finds that
10 assault weapons are not suitable for self-defense and that studies
11 show that assault weapons are statistically not used in self-defense.
12 The legislature finds that assault weapons are not commonly used in
13 self-defense and that any proliferation is not the result of the
14 assault weapon being well-suited for self-defense, hunting, or
15 sporting purposes. Rather, increased sales are the result of the gun
16 industry's concerted efforts to sell more guns to a civilian market.
17 The legislature finds that the gun industry has specifically marketed
18 these weapons as "tactical," "hyper masculine," and "military style"
19 in manner that overtly appeals to troubled young men intent on
20 becoming the next mass shooter. The legislature intends to limit the
21 prospective sale of assault weapons, while allowing existing legal
22 owners to retain the assault weapons they currently own.
23 Sec. 2. RCW 9.41.010 and 2022 c 105 s 2 and 2022 c 104 s 2 are
24 each reenacted and amended to read as follows:
