Leadership must first acknowledged the problem exists. I once watched this movie released by Linda Ikeji where there or four students were attacked by mob, beaten and burned alive because of something they didn't do. Still, the police and even the school administrators never talked about the jungle justice of a thing that was done, regardless of what caused it.
In my opinion, if our leaders, I mean school leadership want to really do better. They should start by taking this mob of a thing seriously just like they take other things seriously. They should release a memo or rules that there will always be a capital punishment for any student that engaged in the mob activity because it is an act of violence that deserves not to be taken with a careless hand.
All schools, or majority of schools have Student Unions for a reason, they have hostels porters for a reason some even have guards. These people should be trained because they are likely to be the first responder in such situation. They have much information at hand and who to talk in such situation. And just like anonymous TV that some people usually do, the school authority should also have eyes in all corners of the school that will be reporting how things are going most especially if things want to go south.
I don't want to talk about that religion aspect because it's so tiring when I see some religious people being killed by people of other religions faith and yet, nothing is being done....
