What began a vile, racist chant by members of University of Oklahoma fraternity has become a legal battle: does the Constitution protect it? Civil liberties attorney Harvey Silverglate and Tufts University history professor Peniel Joseph debate the limits of free speech.

Tonight's caucus members are The BASE founder Robert Lewis, Jr., Boston Herald contributing columnist Jennifer Braceras, and former candidate for Massachusetts governor Juliette Kayyem. They cover the Pamela Smart case, the First Amendment debate, and Boston's Olympics bid.

Boston native and Jim's favorite author Dennis Lehane discusses his new book, which includes a character you just might recognize.

Finally, Jim calls himself a hypocrite for continuing to cover the Boston St. Patrick's Day breakfast and complain about it the next morning. But this year, the parade is the real story.
