"In the criminal justice system, the people are represented by two separate, yet equally important groups: the police, who investigate crime, and the district attorneys who prosecute the offenders. These are their stories."

So begins the hour long drama that's two shows built in one. A half-hour of investigating and whipping out the 'cuffs, and a half-hour of law books and courtrooms. The perfect combination.

I've compiled a list of characers from both parts of the show. For each one, I've listed the seasons in which they appear, things to look for, and what I think of the characer. I've also written a song, and made a list of what I've learned from the show.
