UPDATE: Sept. 20 Orange County Public Schools changed its tune shortly after announcing that it would make students bring a written note from a parent if they wanted to kneel during the national anthem, which would be an interpretation of state law as it pertains to the pledge of allegiance. The district corrected its earlier statement, saying this week:

If a student or staff member kneels or otherwise demonstrates their objection during the singing or playing of our National Anthem at a public event, there is no legal mechanism by which to discipline the individual as a result of this act. However, if their actions are disruptive discipline may be imposed. Unlike the provisions in the law regarding the pledge of allegiance, a written note from a parent is not required. The OCPS Office of Legal Services will be reviewing this matter to insure compliance with all applicable legal decisions and statutes.

Earlier:

Floridas Orange County Public Schools announced this week that their students must have parental permission if they want to kneel during the national anthem at football games.

The move comes after students in at least one school district in the state reportedly knelt in solidarity with 49ers quarterback Colin Kaepernicks protest against social injustice in America.

District officials told WSBTV that they were following state law regarding the pledge of allegiance , a strict and controversial statute that requires unadulterated participation in patriotic gestures.

The statute reads, in part:

Each district school board may adopt rules to require, in all of the schools of the district, programs of a patriotic nature to encourage greater respect for the government of the United States and its national anthem and flag ... When the national anthem is played, students and all civilians shall stand at attention, men removing the headdress, except when such headdress is worn for religious purposes ... Upon written request by his or her parent, the student must be excused from reciting the [pledge of allegiance], including standing and placing the right hand over his or her heart. When the pledge is given, unexcused students must show full respect to the flag by standing at attention

Other school districts are punishing students who dont follow state law. In Collier County, one principal is telling students that theyll be sent home if they dont stand during the anthem during sporting events, WFLA reports.

You will stand and you will stay quiet, Lely High School Principal Ryan Nemeth announced. If you dont, you are going to be sent home and youre not going to have a refund of your ticket price.

Of course, such statutes fly in the face of Kaepernicks protest (and the right to protest in general), but theyre also less lenient than in other states.

In Washington state, for example, students have the right to choose if they want to take part in the pledge:

[Schools] shall cause appropriate flag exercises to be held in each classroom at the beginning of the school day, and in every school at the opening of all school assemblies, at which exercises those pupils so desiring shall recite the following salute to the flag.

The debate over how much freedom students have rages on in Florida. State lawmakers introducing a bill in February argued that too many disclaimers were being posted notifying students of their right to opt out of the pledge via parental permission. The bill would have put that disclaimer into student handbooks rather than conspicuous places on campus, though it would later die.

Forcing students to stand at all may be unconstitutional. In fact, previous decisions in the 11th Circuit Court of Appeals have found that the portion of Florida law requiring students to stand at attention violated the First Amendment.
