Answer to 1 'New Boy'

I think the story tell me the beginning of friendship of children. At the beginning of this story, the new kid from Africa seemed to be confused to the new school and friends. However, after he had a little opportunity, he made friends with some children. I think the filmmaker would tell even if the new boy come to new class, he can get along with others by seizing an opportunity, so I thought it was not so heavy story. The most favorite scene was when the new boy and other children were kept standing outside of the class room as a punishment. They made friends with each other throgh sharing the experiences.
But I couldn't understand the scene which the African teacher was arrested by soldirs. What did it show me? I want to know the detail.
