in the case of actual breaking of the law. I am sure he will punish them, but that is not a substitute for the law.
As for the water ballooners saying they caused it who really cares. The law doesn't say that someone tossing a waterballoon at you is justification for breaking into two apartments.
I think this thing is minor, but I will be extremely disappointed in the justice system if they just drop the charges for this. They should absolutely be charged and convicted of a misdemeanor. If tonight I decided to kick in my neighbors door, I can guarantee if the police catch me that something is going on my record.
