A student threw a racket on the wall in anger and bounced back to hurt innocent students, causing minor injuries. How to deal with it, how to determine the responsibility?

No matter whether the student intentionally or unintentionally throws something back to hurt his classmates, he should be responsible, because the consequences are caused by this classmate throwing things, so this classmate needs to be responsible. As for how to be responsible, first of all, it depends on whether this classmate is an adult. If he is an adult, he will have to pay for treatment, lost time and other compensation. If the injured person is identified as a minor injury, there is no need to bear criminal responsibility because the classmate did not intentionally hurt. But compensation is necessary. Then, if the classmate who throws things is not an adult, his guardian will be liable for compensation.
