Poilce.

You are the cleaner of the poilce station, and one night, while cleaning, you saw a case was going the wrong way, so you fixed it. But then the next morning, the chief poilce officer saw that the case was changed! And they checked the security cameras and saw it was you, so then you were called in for questioning, and they asked you why you changed the case and you explained it was that you took a lot of classes and passed them all and it helped you understand things. and they told you, "either help or go to jail for changing a case." (You decide what happens next + your answer!!) Have fun!!
