You can see the mod as containing two events a function event, the interrogation and a graffiti event, just to show how the function event can be used. The interrogation is a kind of minigame: the task is to find the student(s) responsible. To this extent you ask questions who was there later/earlier arived at the same time, and you can accuse/let go someone. The earliest students at the scnen should have done it. Some may be lying, but most speak the truth - some may refuse to answer for reasons. You have to guess who.
Currently there's not much of a consequence to this, except for some stat changes - overseeing teacher and accused student - dependent on whether you found the right student(s) or not. The graffiti event was just to show how the interrogation event can be used, and I thought a minigame like this, once or twice in the game could be something a bit fun. One could extend the consequences with a punishment event or so.
Off topic, but another idea I had was to locate someone in the city based on who had seen him/her where, haven't worked that out yet, though.
