The panel for the 5th U.S. Circuit on Thursday upheld Texas’ campus carry law, affirming a lower court ruling from last July. The judges found the professors could not prove their case, which largely centered on First Amendment grounds. The faculty members, three female liberal arts professors whose classwork sometimes touches on controversial subjects such as abortion and unwanted pregnancies, argued the carry of guns in their classes would chill open and frank discussion, thus hindering their right to free speech.
