When Gov. Jerry Brown of California signed legislation this month banning concealed weapons on school campuses, the nation was in the midst of one of the worst spasms of gun violence at colleges in recent years. There were three such shootings, including one in Oregon that left 10 people dead, as the bill sat on Mr. Brown’s desk. But the new California law went against the grain of what lawmakers in many other states have sought to do. Over the past two years, nearly 15 states have debated legislation to make it easier for teachers, students and administrators to carry concealed weapons on campus. Supporters say the best way to subdue a campus assailant is ensuring that certain people on the scene can mount an armed response before the police arrive.
