<human>: I study in a well-known private school in my country (in South America) which used to be known for being tough on its students, but nowadays is a mess. During the past few years this school, which used to be a role model for excellence in education, has undergone major problems with student behavior and has done nothing about it. From what I talked with teachers, there have been cases in which the student was expelled or suspended, sued the school and actually won the case. 

That is why these days teachers have to be nice and politely ask stupid douchebags to leave the class, every fucking day, and our counselor has to take care when he tells his students that he is "very disappointed" because they sing profanities in front of tons of children and a few of the most important people of the school, embarrassing him and endangering his job.

My question is: what can be done to stop this? There has to be a way to protect the school from being sued over stupid things by idiots who deserved worse. 

I'm graduating this year and will hopefully never have to see these douchebags again in my life, but I think of other good students, and specially some friends and my little brother, who will stay there, and really don't want them to go through the mess my class is going because of a handful of dumbasses.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My school is afraid of punishing its bad students over fear they might sue, how can the school protect itself and what can the (good) students do to help?
