Are school bans on hugging justified?

Today's students are an affectionate bunch, throwing their arms around each other with a casualness and frequency that has some school officials worried. Concerned with marathon hugging sessions that clog hallways, cause tardiness, and also raise administrators' fears about sexual-harassment suits, some schools have set time limits on hugs (such as a three-second rule), while others have banned them altogether. Students have balked, arguing that such rules are unreasonable and infringe on their personal rights. Does hugging have a place in America's schools? Tell us what you think!
