They sure did. It was planned. Which is why the majority of them went to school that day wearing black leggings and booty shorts.
Since they lost their privileges they want to feign ignorance. They threw the cameraman under the bus. They didn't know what he was going to do with the video. Yea, right! What did they think he was going to do with it? Erase it?
West African culture? Sexism? Racism? How about they broke the rules. Plain and simple.
Many of us remember a time when school faculty and administrators turned their heads when we were doing such things. If they didn't see it, it didn't happen. Times have changed. Social media busted them. If the faculty did not see what was going on that day, someone brought it to their attention. They had to address it because these idiots aired their dirty laundry for the whole world to see.
White girls are not the only ones being punished for breaking the rules. In Ohio and Michigan, male students were suspended for making a Harlem shake video and airing it. Just a couple of years ago, students were being suspended for Tebowing.
It's not that deep. Break the rules in school and you are punished.
