Every now and again, a “CSI” comes up with an episode so whacko, you got to give credit where credit’s due. This week, it was “CSI: NY,” with the episode entitled “White Gold.” Man oh man, was this a crazy one. We started off with two teens tagging a meat plant or whatever with “Meat is murder”-type graffiti. A car and van in hot pursuit blare by, and they hear a crash. The girl goes to check it out, when shots ring out and they run to look and see a body lying there and no sign of either car or van.
