Like more than one other episode this season, this was a great show except for the whole theatrical element. Evidently there has been a mysterious gang of thugs brutally beating people all over the city for no apparent reason. Things get immediately interesting when Greg stumbles across the gang in the middle of one of their beatings and tries to break it up.
As I would have done, he backs up his Denali and drives toward them honking his horn with his police lights flashing. All of the thugs run except for one, who is made to look like a horror movie psycho who is completely fearless of the police, and instead of running away, he charges toward Greg's truck with a rock in his hand.
The episode starts off really good with the sudden sense of danger falling over the city because the attacks are so brutal and so random. It very effectively takes away that real life sense of safety that we have in our everyday lives, but then it falters because we get these psychotic teenagers beating people to death. I know we live in a violent world and I know that Vegas is the Sin City, but kids just don't do that.
One of them is caught and questioned, and after arrogantly snapping at every question the police ask her and generally acting like a high school girl lashing out at her parents, she admits that she and her "friends" regularly get together and beat random tourists within an inch of their lives just because they get tired of seeing them everywhere.
It's not uncommon for CSI to give us murder cases that happen under wildly outlandish situations (remember the guy who killed himself with the gun tied to a piece of elastic that pulled it up the chimney after he shot himself?), but this is an example of one of the stories that was just a little too unrealistic as far as basic human behavior.
Oh and yeah, Kevin Federline was in it. Who cares.
