In the vice presidential debate Tuesday, Minnesota Gov. Tim Walz pulled the fire alarm.
His opponent, Sen. JD Vance, R-Ohio, cited the massive system of censorship supported by Vice President Kamala Harris and her running mate.
Walz proceeded to quote the line from a 1919 case in which Supreme Court Justice Oliver Wendell Holmes said you do not have the right to falsely yell fire in a crowded theater.
It is the favorite mantra of the anti-free speech movement. It also is fundamentally wrong.
