Maybe the professor isn’t familiar with the Protection of Legal Commerce in Arms Act . . .
Consider this out-of-the-box proposal: Liberal, pro-gun-control states could apply the Texas bounty approach to gun control. New York or Illinois, for example, could declare that gun crime has gotten so serious that the private ownership of most handguns should be deterred. It would be unconstitutional for the state to authorize the criminal prosecution of those who facilitate constitutionally protected gun ownership. But the state could, instead, enact a gun-bounty civil law modeled on the Texas abortion law. It would empower any citizen to sue for $10,000 anyone who facilitates the sale or ownership of handguns.
Gun-ownership advocates would rail against such a law as circumventing Heller, just as abortion advocates are railing against the Texas law as circumventing Roe. But it would be hard for the courts to uphold the civil mechanism of the anti-abortion law without also upholding the identical mechanism in the anti-gun law.
Creating this “shoe on the other foot” challenge would bring home the dangerous implications of the Texas bounty approach which, if not stopped, could undercut the authority of the Supreme Court to enforce other constitutional rights.
Texas could, for example, next apply it to gay marriage — any private citizen could sue anyone who performed or facilitated same-sex marriages — thus circumventing Obergefell v. Hodges. New York could then apply it to Citizens United v. FCC and offer a civil bounty to sue any media outlet that ran corporate political ads. Any state could simply target any Supreme Court precedent it doesn’t like and deter its enforcement by authorizing citizens who oppose it to sue. This would empower every state to effectively overrule Supreme Court decisions, as some southern states unsuccessfully tried to do following Brown v Board of Education in 1954.
