The families of the Sandy Hook massacre victims say gun maker Remington marketed a killing machine to the public.
That was an argument made to the Connecticut Supreme Court by families of several victims of the 2012 school massacre.
The plaintiffs argue that Remington marketed the assault rifle to people like Adam Lanza, who killed 20 children and six adults with the rifle.
A lower court previously dismissed the lawsuit, saying federal law gives gun makers broad immunity from actions of people who use their products.
