Justin Watt, a Tar Heel living in California (and regular reader of GreeneSpace), saw this billboard and created this blog entry. He got a big-foot letter from Liberty Counsel on behalf of the billboard's sponsors. Jason persuaded the ACLU to write a powerful letter defending his right of fair use in the form of parody for social comment. Liberty Counsel has apparently backed off. This is wonderful--but how many big-foot letters end up intimidating the recipient and silencing lawful speech? Congratulations to Justin for knowing his rights and acting on them.
