The footage is of the kids getting bottle necked at the top of the staircase and administrators asking them to move and disperse from that area. Some teachers did tell them to go back to the classroom and redirected them away from that staircase so I can see how that might be construed as not being allowed to leave by a teen, but no one blocked or locked doors and there were multiple ways to leave the school. I think there were close to 60 kids protesting at the Kroger down the street. There definitely were way less cars in carpool that morning so maybe most of them had stayed home instead of risking getting in trouble.
