Plaintiffs’ complaint alleges that defendants, through their actions, carelessly facilitated Adam Lanza’s acquisition of a weapon of war, thereby enabling the slaughter of twenty first-grade children and six adults. This allegation states a claim for negligent entrustment as that common law tort is properly construed; a rigid or formulaic analysis is not required. Alternatively, to the extent it must adapt existing law in order to endorse plaintiffs’ cause of action, this Court should do so, recognizing that the common law’s “genius” is its “flexibility” and capacity for “adaptation.” State v. Skakel, 276 Conn. 633, 691 (2006) (internal quotation marks omitted).
