Weapons of Mass Destruction (WMD) are defined in US law (18 USC §2332a) as:
“(A) any destructive device as defined in section 921 of this title (i.e. explosive device);
(B) any weapon that is designed or intended to cause death or serious bodily injury through the release, dissemination, or impact of toxic or poisonous chemicals, or their precursors;
(C) any weapon involving a biological agent, toxin, or vector (as those terms are defined in section 178 of this title)(D) any weapon that is designed to release radiation or radioactivity at a level dangerous to human life.”
This petition is to amend that law to define firearms having a magazine of more than 5 bullets as a WMD unless in the hands of military or state or local law enforcement being used on active duty.
