Ok, now we are really getting into First Amendment territory. The Sheriff's Dept, a government entity, is stating they will no longer give escort service to the Dolphins because they don't stand for the Anthem. Definitely a violation of the players' First Amendment rights. They should be contacting the ACLU over this, IMO.
I would re-write every players contract. New Terms of Employment require you stand for the National Anthem. If not, discipline is warranted
