10/11/03 Episode 2.2 They really need to do a better job of introducing cop characters on the show because people just show up and then we get tidbits about them, but it's a little annoying. So Roselyn Sanchez gets transferred to Joe's department/unit. Does she replace the other latina officer from the first episode of this season? The case itself was more useful as a litmus test for Sanchez's character, than being all that interesting. Joe is still the man with the insights and instincts.
