Security guards at the 9/11 Memorial didn't appreciate it when a group of middle school kids visiting from North Carolina began singing the Star-Spangled Banner.

Waynesville Middle School music teacher, Martha Brown told the NY Post that one guard yelled at the students to stop.







“You have to stop. This is considered a public demonstration!” he cried, according to Brown.



The group of kids apparently needed a permit in order to be allowed to sing.

“Some of the students were very upset and confused. I told the children, ‘This is a place where you need to respect authority even if you don’t understand it,” she said.



The children were nearly finished the anthem when the security guards stepped in.



One mother filmed the incident and put it on Facebook where it has been viewed over 300,000 times.

“So sad this is happening everywhere. They sounded great. God Bless America!” Connie Shepherd Scanlon wrote.



A spokeswoman for the 9/11 Memorial has admitted that they were in the wrong.



“The guard did not respond appropriately. We are working with our security staff to ensure that this does not happen again with future student performances,” she said.
