He moved to Hawaii a few years later and became a detective

I bet when Johnny Gat left the scene of his dad's murder, he went home, took off his suit, dressed himself all in purple, and along with his crew, the Third Street Saints, he went after the people who did it.

Do you have the clip or season number episode number and title when Andy helped a older lady with her her money being stolen? I was trying to find a scene where Andy handcuffed the guy to the closet pole and told them maid to watch him and then he was able to convince the lady to press charges on a guy for laundering her money.

America Free country, the money is the king, you can buy almost everything you want.
Using a bounty hunter is legal.
Or a Private Investigator.
You can propose a Reward for info about a crime.
The son of the victim had perfectly understood how it works in USA.
This is far different in France (my country), not sure we have bounty hunter. We have surely some Private Investigator, but they are not very common, and not in our way.  
(The actor playing the son of the victim is the same I thaught that the one playing the corean character in the TV show "Lost", and before in a small secondary rôle in Star Trek Enterprise isn't it ?).

Will the clips from S5E2-4 be posted?
