"It's not our fault, honest Guv!
We only built that nuclear bomb, we didn't deploy it, so we shouldn't be accountable for the actions of the people that did."
"Oh, and we only sell nuclear bombs to legit third parties that pinky swear not to hurt anyone with them, so you can just let us go with a warning, right?"
Replace "nuclear bomb" with a "brick of firecrackers" & it starts sounding like the whinging of most adolescents caught after trying to blow up the neighbor's cat.
Take them out behind the barn, bend them over a hay bale, & take a stout stick to their behinds until you've run out of trees to turn into spanking switches.
