  • With what you know about proportion look and read what is in the image above. Does it seem just and fair?
  • No it is not fair, because Roy stole little money and Paul stole 3 billion dollars and was sent in prison .


  • Why have you made this choice?
  •   Because Pual stole 3 billion dollar and was sent in prison for 40 years and Roy stole 100 dollars and was sent to jail for 15 years.


  • What would you have done if you were the judge
  • I would give Paul R. Allen a longer time in prison and give Roy Bown a sorter time and put him in jail.
