Kim Kataguiri: Look, it's impossible, and this is what I hear most from public school teachers here in the state of São Paulo: you simply can't teach.
Kim Kataguiri: If the teacher has no authority, no authority to punish, no authority to restore order in the classroom.
He can't expel a student who's causing trouble in the classroom, because then he'd be depriving that student of his right to learn.
Kim Kataguiri: In reality... That very student who causes the disruption of the class, who is depriving all the other students of their right to learn and the teacher of his right to teach.
Kim Kataguiri: Imagine, this teacher could have died.
