Part 5

Social Justice

1. Does this seem fair?

It does not seem fair

2. With what you know about proportion look and read what is in the image above. Does it seem just fair?

No, it just does not seem fair

3. Why have you made this choice?

I have made this choice because because the CEO (Paul) was sentenced to only 40 months for committing a scam that got him 3 billion dollars, and the homeless man (Roy)  only took 100 dollars from the bank when the banker gave him much more and was sentenced to 15 years. Another reason is because Paul did it just because he was greedy and Roy did it because he was homeless. 

4. What would you have done if you were the judge?

I would've sentenced Paul to 15-20 years in jail and I would've sentenced Roy 8-12 months in jail. I would've also gave Roy a big speech on how their are other ways he could've got money.
