Jack should go to prison because he decided it would be a good idea to rob a giant 3 times and then chop down the beanstalk and make the giant fall to his death; the things he stole was a bag of gold coins, a golden goose that lays golden eggs and a golden harp that plays by itself, yes he got scammed by the person but it was his fault, he should have known it was a bad idea to trade a cow for three beans.

Well I hope you will find him and report him to the police.
