This episode symbolizes why we're de-listing CSI:NY from our DVR, despite having watched this from Day 1. A few episodes back we realized that we spent more time laughing at and making fun of plot holes in CSI:NY than we did enjoying it. That's too bad.
Another reviewer has summarized some plot holes. Here are a few more: The team analyzes the broken chain from the gate where the cement was buried. They said that the chain broke at 2300 psi, and therefore a car with at least a 350 horsepower engine would have been required to break through. Nonsense. And, stupid nonsense. The amount of force required to break the chain is a function of the mass of the object multiplied by the acceleration of the object (F=M*A). This isn't a function of the horsepower of the engine, it's just about how heavy the car is multiplied by how fast it's going. An engine of 100 horsepower or 350 horsepower doesn't matter. If you're going to make this kind of mistake, it should be for some critical plot element. But after that explanation, the type of car never ends up having to do with the ending. The issue never comes up again. Sloppy, sloppy writing.
The cement mixer they used was so small that it would have taken them hours to cover the body.
After 10 hours underground, and dead, the blood wouldn't have been that liquid-y. And certainly not under enough pressure to come spurting out like that.
The body was too far underground, according to the depth of the concrete, for the jackhammer to have reached it.
There was no hole in the body cause by the jackhammer. One from the horn on the helmet, one from the glass.
For the past two seasons, the writing on this show has gotten steadily sloppier, steadily more ridiculous. That's too bad. Some of my favorite actors are on this show. It was one of only two shows we actually watch regularly. But it's gotten much too silly.
