A stalking injunction blocking a man from contacting, writing about or going within 1,000 feet of Florida Sen. Lauren Book came before the Fourth District Court of Appeal for the second time Wednesday, when the court issued a lengthy and divided en banc opinion.

It was a case in which social media, public officials and the U.S. Constitution collided, giving the court ”the opportunity to address whether First Amendment freedoms have limits when applied to 21st century communications.”
