At two different schools in Wisconsin, administrators ordered the students — two high school sophomores and a middle-schooler — to cover up the T-shirts with jackets and banned them from wearing any gun-themed clothing on campus in the future. In a letter to parents, one superintendent mentioned concerns about violence in schools.

But now the boys and their families are suing, saying the schools violated their constitutional rights. In a string of lawsuits filed earlier this month, they charge that administrators are violating the First Amendment — by preventing the students from wearing clothes supporting the Second Amendment.
