Wu's on First?

Plot:

When a police officer is found shot to death, Elizabeth Wu writes an article praising his dedication to the job. An informer calls her with a contradiction: the cop was shot when he demanded his money back in a dope deal. Her source later reveals that he was the shooter but claims self-defense. Meanwhile Kellerman's rogue brothers show up and he winds up in a jail cell with them. Lewis and Julianna to the rescue.
