One way to address negative externalities is for the government to intervene through subsidies, taxes, or legal constraints on the producer. But when it comes to guns, Republican legislators are overwhelmingly unwilling to take those steps. As happened with the tobacco industry, then, the most practical means of spreading the costs of gun violence is to turn to tort law and the courts. …
President Joe Biden has repeatedly called for Congress to repeal the PLCAA—a virtual impossibility as long as the Senate filibuster exists to kill legislation without a 60-vote supermajority.

Even so, in most cases in the judicial system, the success or failure of lawsuits hinges on discretion. Discretion of judges to let a case survive a motion to dismiss. Discretion of juries to look beyond just the facts and the law and consider the whole picture around a dispute.
