The central argument of Morris’s essay is: although mining students’ data can not perfectly predict the campus violence and may provide issues of getting student private information without permission, this method is still helpful to reduce the possibility of school violence event. I agree with it. By surveilling student’s data on the internet, the school can both protect the student himself and the campus. First, if the school uses the data mining method to get students’ searching frequency and their comments on the social media, the school can analyze the data and find out the reasons that are responsible for the wired behavior. After this, the school can send faculty to solve the metal problems and prevent the situation become more serious. What’s more, if the school solves the students’ metal issues, it will create a healthier environment for studying. With this improvement, it can create a loop that healthier environment will lead to less mental issues. Less mental issues can lead to less campus violence. Thus, mining students’ data creates more benefits compare to doing nothing. However, school should still keep the data private instead of telling the situation to the whole faculty to prevent the violence. The school should use proper methods to solve the students’ metal issues in order to build a safer campus life.
