California's public higher education campuses show a sorry record of censorship in placing limits on student speech, reports Erica Perez for California Watch. Speech codes and free speech zones are teaching a whole generation of grads to tame their tongues and muffle their minds. "A new report from a national free speech advocacy organization," she says, "found most of the four-year universities it surveyed had speech codes that substantially limit students' freedom of speech, including dozens of colleges in California."
