This is the Cato Daily Podcast for Thursday, January 31st, 2013.

I'm Caleb Brown.

From the destruction of free speech walls to draconian and chilling speech codes.

Free expression on campus is under threat.

Greg Lucianov is author of the new book Unlearning Liberty.

We spoke following a forum for the book held last month.

I went to the University of Louisville, one of your red light schools,

and it never struck me particularly as somebody who was active on

campus somebody worked at the student newspaper that there was

particularly a problem and then I hear Miss Jemison talking downstairs at the event and

it seemed that the school where she was having a problem where there was a policy

prohibiting them from even using the word

marijuana on a flyer to advertise an event to discuss the possibility of

the legalization of marijuana that they didn't so much want to infringe on speech, but they wanted a policy

that allowed them to do so should something objectionable come up, which in some ways is even more dangerous than not

having a policy at all?

Well, the way that you end up with a red light or yellow or green light rating it all

depends on what you actually have on the books and that's somewhat separate from

how a university behaves but I can't tell you how many times I've heard people

say that their university is totally fine without knowing

that a student had actually gotten trouble for clearly protected speech maybe in the same year

that they were there.
