[8][9] A Bushmaster XM15-E2S carbine was displayed in a February 2011 video message by Caucasus Emirate leader, Dokka Umarov.

[11] Just before the second anniversary of the massacre, nine families of the 26 victims of the shooting filed a class action lawsuit in Connecticut against Bushmaster, Remington Arms and others,[12] seeking "unspecified" damages for the defendants' purported negligent entrustment and illegal marketing of the XM-15 rifle.

[13] Plaintiffs argued that both theories of liability fell within exceptions to the 2005 Protection of Lawful Commerce in Arms Act, which affords broad civil immunity to gun manufacturers.

[16] In March 2019, the Connecticut Supreme Court reinstated the wrongful death lawsuit, holding that the plaintiffs successfully pleaded a cause of action for illegal marketing.

[1] As of October 2, 2000, California has banned the Bushmaster XM15 by name in the Kasler v. Lockyer Assault Weapon List, among other AR-style rifles by Armalite, DPMS, Colt, and Eagle Arms, to name a few.
