I'm not hating on Jack, I think he's really turned his life around for the better. But would a nobody with Jack's documented drug use be allowed on the police force? I have no idea what the criteria for past problems is when joining the police force, maybe it varies from place to place. Just wondering if he wasn't a star would they overlook his past.
But, to Jack's credit he seems to take the serve and protect motto seriously. Most stars want to serve themselves and protect their assets.
