1. Does this seem fair?
   - No, i do not think it's fair
   
   
2. With what you know about proportion look and read what is in the image above. Does it seem just and fair? Why have you made this choice?
   - I do not think it's fair because the first man stole way more money than Roy Brown. He felt guilty and he turned him self in. Paul Allen didn't.
   
   
   
3. What would you have done if you were the judge?
   - I would let Roy brown be in jail for 5 months
