Does this sound unfair?

at my school this kid during an indoor period took disinfecting spray and sprayed it in many kids faces three kids went home because of allergic reactions. All the boys in my cl are going to be suspended and one of my friends who is a girl who was sitting down when the whole thing happened if something like this happens again. everyone say this one kid doing this and people are being blamed and they had nothing to do with it so please speak your mind
