You could have avoided a lot of the questions asked in this thread by simply posting more information from the article:
Instead of doing as they were instructed, Gassman said the students resumed the song – an impromptu form of civil disobedience.
“If their idea of civil disobedience is singing the national anthem, then so be it,” Gassman said. “Let them disobey.”
YAF posted video reportedly shot just after the alleged encounter with the security officer. It shows students loudly singing the anthem.

Less provocative and more informative.

“Instead of doing as they were instructed”???
The question here is why a group shouldn’t be allowed to sing the National Anthem when according to another post, “Pinatas parties and Muslim prayer meeting are authorized at the memorial, if kept low key. However American patriot songs and American flag T-shirts are not allow...These rules have been in effect for years and were implemented so as not to offend foreigners.” If this is true, every group of American Citizens that visit the Lincoln Memorial should sing the National Anthem.
