Pepper-spray. People will learn not to haze others, once they get pepper-sprayed. I'm sorry if this won't help i dropped outta school in 9th grade because of bullying and getting hazed.
Training and educating students about the dangerous risks and potential harm caused by hazing. Traditions of hazing need to be phased out of education and only way to do that is through reeducating the students and changing mindsets.
In addition if you witness any hazing or are aware of it be encouraged to call 911 and report it. Hazing is illegal. Students should be encourage to report them.
