Numb3rs: The O.G.

1,350 L.A. street gangs. 152,000 gang members. 504 homicides. 2.2 square miles. CBS must have thing for crime stories involving gangs because they had a very similar plot just the other night on Without a Trace. This one was a better story though and it had a pretty good twist at the end especially if you consider an episode from a few weeks ago (the Bill Nye one) because it led you in the same direction and turned.

An undercover FBI agent was killed by some gang members in a drive-by shooting, but it was determined that his cover wasn't blown so the question became why was he killed then? The FBI gets some help from the LAPD's gang task unit, led by a jerk captain in a nice cameo by Will Patton. Charlie ran some ridiculous equations dealing with the almost 8,000 gang related shootings over the past year and he came up with the conclusion that one person had been responsible for 8 deaths and the 52 others that resulted from retaliation. One guy caused 60 deaths including the undercover agent's. That's crazy.

For a while we were led to believe that the gang unit's captain was behind it all because he had access to confiscated guns and an intense knowledge of the gangs and their leaders. This would have been the same thing that happened in the Bill Nye episode when the arson investigator ended up being the arsonist. But it ended up just being a regular guy who worked at a community center and lost a son in a shooting a few years back. He wanted revenge and his one killing led to a ton more.

Now a few gripes. Once again, why hasn't Colby (played by Dylan Bruno) been made a full cast member? He was all over this episode and Navi Rawat had about two seconds in it. Also what is the deal with romances in this show and how they just disappear? What happened to the D.A. that Don was seeing and what about the date between Larry and Megan that was mentioned about a month ago? The writers just seemed to forget about these. I hope they get brought up again because it seems weird for them to just vanish after they've been mentioned.
