Why is it you never see pudding used as evidence on CSI or NCIS?

Because pudding and pudding cups were at the crux of a case so big and so serious it took 5 years to bring it to court. Here's the backstory courtesy of The Jersey Journal:

Efrain Rivera, 52, of Jersey City faced burglary and theft charges stemming from a May 2008 incident where a Jewett Avenue man had more than $8,000 in power tools stolen from his basement apartment. 

The assistant prosecutor had linked Rivera to the scene through DNA evidence taken from two cups of Boost pudding and a bottle of cranberry juice.

That's all Hudson County Assistant Prosecutor Jason Cieri needed, somebody's DNA on a pudding cup.

So there you have it readers, his DNA was all up in those pudding cups and therefore he took the tools. 

But, wait, hold on a minute...

Nope, the DNA says he did it, he ate pudding now he must pay for his crimes.

It would seem to most people you'd want to ask...

Nope, open and shut case because PUDDING!

It took a jury of his peers a mere two hours to declare Mr. Rivera not guilty. Somebody in the prosecutor's office might have thought to, in these last five years, ask if Rivera had business in that apartment building. He had several legitimate contacts and reasons to be in the building it turns out according to his attorney and witnesses who testified in court.

Several legitimate contacts. Five years. Extensive pudding cup DNA tests. Court and attorney fees. Well done indeed.

Woodrow Miller needs to spend MORE time in front of the TeeVee watching CSI and Forensic Files

Ya see Woodrow, if you're going to clean up a POSSIBLE murder scene (Miller as you may recall was the only other person at the scene of the shooting of Quaneera Adams who sadly died from the gunshot) while the victim lies alive on the bed and THEN call 911 you not only look guilty as hell, you're gonna bring the full force of criminologists down on your dumb ass.

You cleaned up the scene BEFORE calling 911? Gee, nothing strange about that now is there Woodrow? We're also sure the blood on your clothing was a coincidence.

Miller has been arrested in connection with the crime but has not as of yet been charged with murder.

Johnny hears they have teevee in prison where people like Miller can catch up on watching CSI and Forensic Files.
