To support Breast Cancer Awareness month, two middle-school girls wore bracelets that said “I (Heart) Boobies.” But when they got to school, they were told the bracelets were inappropriate and they had to take them off. When they refused, they were suspended. The principal, a breast cancer survivor, said the bracelets trivialize a serious issue, and the double entendre was prohibited under the school’s dress policy. But the girls decided to make a case of it — a federal case, as it were — so I invited their attorney, Mary Catherine Roper of the ACLU to explain their side on my America Weekend show. She explained their free-speech argument, and what Supreme Court precedent says about student expression.
