Here is a quote credited to a DPS teacher: "One third grade teacher wrote, “Students have no fear of breaking rules. I have had students who attack others regularly, throw chairs at students’ heads, punch students and teachers in the face, choke others, stab at necks with fists full of pencils, curse violently, run out of the school, elaborate on their plans to harm others at the school or get them to commit suicide — and those are just my students.”

Taking the kids out of the classroom keeps the other kids safe and allows for them to have a chance at learning without as mush disruption. Maybe they can move the violent kids to a violent kid classroom instead, I don't care. They are not learning to deal with consequences  at home, school is their only shot. 

It's not just me, it sounds like a majority of teachers who have commented are against this.
