Nashville magistrate Tom Nelson has said there's no legal reason in his city to keep the demonstrators behind bars and he has released them after each arrest. He has refused each night to sign off on arrest warrants for more than two dozen people taken into custody.
Some legal experts agreed with the judge.
"You can't pass a curfew mid-protest because you disagree with this group of protesters," said criminal defense attorney Patrick Frogge, who is representing some of those arrested.
