A court case that originated in Virginia has now set legal precedent.
The Fourth Circuit Court of Appeals has ruled that Facebook likes are protected speech under the first amendment.
The case began in 2009, when the incumbent sheriff of Hampton, Va., B.J. Roberts was running for re-election.
During the election, some deputies on Roberts' staff "liked" challenger Jim Adams' Facebook page.
After Roberts won re-election, he fired those employees and they sued.
