Please fire the Capitol policemen that yelled at and threaten with arrest small children, as young as 3 years old.

Please fire the Capitol policemen that yelled at and threaten with arrest small children, as young as 3 years old, that were singing in a hallway. Regardless of one's political views, these officers were aggressive, repressive, and unbecoming of their profession. See https://www.youtube.com/watch?v=8JJ8-3nQMGM
These men reveal an unstable mind set and they should not be allowed to work there. The Capitol is a symbol of American democracy; yelling at small children, and threatening them with arrest for exercising their rights, has no place in there.
The officer saying: "We do not sing in the hallway. Comprende?" is infuriating and highly reprehensible. To display such a racist and aggressive behavior towards an adult is disrespectful, but to do that to children is child abuse.
